This example visualizes a small dataset of college football teams by encoding each team’s identity directly as a color hue. Five circles, one per team, are arranged horizontally, with each circle’s fill color matching a team-specific value from the dataset. The code uses D3.js (version 3.5.5) to select and append SVG circles, binding the data array that pairs team names with colors. The rendering approach relies on SVG attributes like `cx`, `cy`, `r`, and `fill`, with the fill determined by the second element of each data pair. The data source is a subset of a passing yards dataset, provided via gist.
