Previously, the log scale's tick format would hide all labels when there was not
enough room to display the requested number of ticks; now it at least displays
the power-of-ten labels. Fixes#655.
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 adds support for filtering the log ticks, such that fewer ticks can be
generated to fit in a small space. This can be used in conjunction with a
custom tick format as well. This commit also changes the default log tick format
to be exponential rather than precision, for consistency.
