Radial Bar Chart
This radial bar chart displays the relative frequency of English letters (A–Z) from a CSV dataset, with each letter’s value encoded as the length of a colored arc segment arranged around a central axis. The segments animate inward from the center using an elastic easing over two seconds, while dashed circular gridlines and a solid outer ring provide scale references. Built with D3 v3, the visualization uses `d3.svg.arc` for the segments, `d3.svg.axis` for the radial scale, and `transition.attrTween` to interpolate each arc’s outer radius during the animation. Labels are placed along a circular path via `textPath`, and letter colors come from an ordinal scale.
