A radial line chart displays Twitter's closing stock price over a year, with time mapped to angle and price to distance from the center. Monthly tick labels and concentric price rings aid reading, while a blue path animates around the circular layout on load. The visualization uses d3.scaleTime, d3.scaleRadial from a custom d3-scale-radial.js file, and d3.lineRadial, with SVG transitions for drawing the trajectory.
