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. |
