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.
There's now a new API for invoking the hierarchy layout (hierarchy.nodes) rather
than calling the layout function directly. Calling the new API enables inlining,
which is disabled by default for backwards-compatibility.
This way, we don't need symlinks (which don't work on Windows). This commit also
simplifies the structure of the flare.json file, so that we don't need to tricky
conversion of the JSON map—it can be read directly by the hierarchy layout.
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.
This method can be used to generate an array of parent+child objects for a given
array of nodes. This is convenient for drawing paths from parent to child in
node-link diagrams.
The `cluster` layout is now more similar to the `tree` layout, using a
separation function rather than a group property. In addition, the breadth and
depth properties are replaced with x and y, respectively, and scaled according
to the size of the layout.
I've updated the examples to make them more consistent, as well, including the
pretty Bézier curves. In a future commit I'd like to take some of the duplicate
code in the examples and move that into reusable methods.
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.
