This fixes a crash with the symbol type "hasOwnProperty", rather than defaulting
to "circle". This commit also adds new map methods to retrieve the keys, values
and entries. The map class now uses non-enumerable properties (if supported).
This is, essentially, an ES6 shim for a Harmony Map. We will use it instead of
using a bare object, so that we don't need to worry about collision with built-
in properties names (such as "__proto__" and "hasOwnProperty").
This commit provides a standard interface for time intervals:
interval.floor(date)
interval.ceil(date)
interval.offset(date, k)
interval.range(start, stop, step)
All local-time intervals (such as d3.time.day) have a UTC-equivalent interval,
available as interval.utc (such as d3.time.day.utc).
Fixes#463. Note that for the time.scale, an interval function is required to
nice (such as d3.time.day). In the future, we might relax that to allow a count
of ticks, similar to the ticks method, but in that case we'd also need the
ability to floor to a given tick number (e.g., every other week) and likewise
for ceil. This seems like a reasonable first implementation.
Rather than having two implementations for local time and UTC time, we now have
a single local-time implementation and use d3_time_utc to adapt for UTC.
Rather than producing separate files for each module, the default build now
produces a single file. This should encourage better page-load performance as
the files were relatively small. Also, it's easier to deal with only one file
rather than many, especially if you're not quite sure what the dependencies are.
You may still create minimized builds, if you don't want every feature.
This commit also demotes the chart components to the examples directory, rather
than keeping them as part of the core library. As always, D3 is not a charting
library, and these were ever only intended to serve as examples.
This includes a d3.extent convenience method for [d3.min, d3.max], and fixes the
brush component such that the resizers are hidden when the extent is empty.
You can now query the brush for its selection. This commit also includes a new
d3.random.normal for generating random numbers with a normal distribution. This
is useful for jittering points for display.
The d3.svg.brush component allows one- or two-dimensional rectangular brushing.
A future commit will allow the brushed region to be resized by grabbing an edge,
and also provide some way of reporting the selection (duh)!
Due to the ordering in which the prototypes are defined, it was still undefined!
Also, the empty method depends on the node method being defined. Added a test.
Quote from NEWS file:
In previous versions of make it was acceptable to list one or more explicit
targets followed by one or more pattern targets in the same rule and it
worked "as expected". However, this was not documented as acceptable and if
you listed any explicit targets AFTER the pattern targets, the entire rule
would be mis-parsed. This release removes this ability completely: make
will generate an error message if you mix explicit and pattern targets in
the same rule.
There is also a greatCircle as an alias, whose angle defaults to 90 degrees. (Or
should, but some projections cannot handle 90 degrees so we use 89 instead.)
The greatArc class is the new name for greatCircle, which actually represents
great arcs. Meanwhile, a new greatCircle class is for great circles. The new
greatCircle class replaces the old clip class, providing clipping and resampling
functionality (using greatArc internally). This isn't backwards-compatible, but
I may forgo the major version number bump in light of the fact that greatCircle
was just added, and not used in any (official) examples or documented.
Note that the Werner projection is a special case with standard parallel
at 90°N, and the Sinusoidal projection is also a special case with
standard parallel at 0°N.
This can be used with d3.geo.path.clip to clip the input coordinates of
geographical shapes using a given origin and angular radius, e.g. for
hemispherical or near-hemispherical views. Geodesics are inserted as
necessary.
This also includes a minor bugfix and test for d3.geo.path: the last
coordinate of Polygon features was being included unnecessarily
(MultiPolygon already handled this correctly).
IE9 does not string-coerce values, instead throwing an error. We now wrap IE9's
implementation to force string coercion. While it would be simpler to turn on
string-coercion for all browsers inside D3's style operator, this approach
avoids penalizing standards-compliant browsers.
This commit also moves language-compatibility code to a separate directory, and
deletes the obsolete Object.create polyfill, which is no longer needed by D3.
Can be used to generate great circle paths. Similar to R's
geosphere.gcIntermediate (in which I discovered a bug, while writing the
test case for this!)
Includes d3.geo.greatcircle().distance for computing the shortest geo
path distance using the Haversine formula.

This fixes a breakage on IE9, which doesn't support array subclassing through
prototype injection. On IE9, we then use direct extension of the prototype, but
this can only be done after the prototype is fully-defined.
This also fixes a few bugs in the new implementation, restoring support for the
offset between the mouse and the dragged element by reporting a delta rather
than an absolute offset. Also, this fixes an infinite loop when an element is
removed from the DOM.
I'm including the axis component in the core build because it should be useful
in many different visualization types, similar to the other svg components. The
chart module contains a hodgepodge of more obscure visualization types, and
there's no reason to pull those in for more common visualizations. Perhaps most
importantly, the axis component isn't a chart type!
Extracted from d3.layout.force. Fires "dragstart", "drag" and "dragend"
events, with a "position" property. Note: this introduces a dependency
on d3.behavior to d3.layout.force if used (in addition to the existing
dependency on d3.geom).
Fixes#249.
This changes the core implementation of selections and transitions to use
prototype injection rather than direct extension. This offers better performance
by eliminating per-instance overhead from closures and assignment. On browsers
that don't support prototype injection, we fall back to direct extension.
This commit isn't just about performance, though; the code ends up being a lot
cleaner and more separable if we force methods to rely solely on `this`, rather
than capturing surrounding variables with closures.
Most importantly, transitions are now "transparent", like selections. Rather
than opaque objects, transitions are now arrays of nodes, similar to selections.
The nodes are wrapped in an object that stores the delay and duration, which
means you can now inspect the computed delay and duration. (This was the
original motivation for this commit, and will allow chart components to be
call'd on transitions as well as selections.)
Transitions now support the `each` operator with one argument, which has the
same behavior as on selections. The `each` operator now passes a third argument
containing the group index (`j`). Transitions now also support a `tween`
operator, which is a generic mechanism for doing things during a transition; use
this in place of a "tick" event.
This commit also fixes a few bugs. The enter selection now supports the empty
operator; we can add other operators in the future more easily, if we so choose.
Transition's attr operator now supports namespaced attributes. Selection's
property operator no longer parses property namespaces.
This is the simplest possible implementation. It does not yet support updating
an existing display, specifying different scales for different instances,
overriding ticks, overriding tick format, transitions, etc. etc.
This is similar to pv.search, but more closely modeled after Python's bisect
methods to provide the desired flexibility in searching slices of arrays. This
includes good tests for bisect, and better tests for polylinear and quantile
scales (both of which now use bisect).
This commit adds a d3_uninterpolate method (private, for now), which is
essentially the inverse of d3.interpolate. It's used to map a value in the
domain to the unit range [0,1], which can then be passed to an interpolator.
This is a utility for creating a Bézier curve between opposite corners of a
rectangle. This is commonly used to draw smooth curves connecting parent and
child nodes in a hierarchical node-link diagram. A projection may be specified
which allows the curve to be transformed from polar coordinates.
This commit also changes the semantics of the recently-added `links` method,
such that the objects have `source` and `target` properties that match the
default diagonal format.
Based on the Protovis version. The only difference is that I've dropped
the `orient`, `innerRadius` and `outerRadius` properties so that the D3
version is more flexible.
Based on the Protovis layout. I've kept the convention of using `size`
for the width/height and `separation` for the spacing. The Protovis
layout had a `size` property but this was used to compute the radius.
I've left this out as I've assumed it's straightforward enough to pass
in the appropriate `radius` function instead. Likewise, I think the
existing hierarchy `sort` property can handle situations that `order`
was intended for in the Protovis version.
UglifyJS requires Node.js to run, but it's a lot faster than Google's
compiler and produces smaller gzipped sizes. Some of the non-gzipped
sizes are a bit larger than Google's but I think the gzipped size is
more important. Faster runtime is also good when we start testing the
minified versions too.
First, we were using the wrong space-filling format for %d and equivalent.
Second, we weren't parsing numbers with optional leading spaces correctly.
Yay tests!
This was breaking setTimeout and setInterval in Node, since I've already
unplugged env-js' event loop. With that out of the way, we can write tests for
transitions!
The Selectors API guarantees that results are returned in document order, but
Sizzle does not, by default. So now we sort the results when using Sizzle. Yay
tests!
This adds d3.layout.pie, which can be used to compute the start and end angles
for arcs given an arbitrary array of data. In addition, d3.svg.arc now has a
`centroid` method that computes the center of the arc, useful for labeling.
Together these changes greatly simplify the donut & pie examples.
This commit also includes a `map` method for selections, which is similar to the
`filter` method. This allows you to map the data bound to the current selection.
I'm not currently using it, but it seems like a useful feature for those cases
where you want to rebind the current selection to different (but related) data.
