This visualization shows the average selling price of cars grouped by make, using a horizontal bar chart where each bar’s length encodes price and its color denotes the car make. The chart, built with React and D3 v5, loads CSV data from a GitHub gist, aggregates the selling prices by make, and renders the result as SVG. It employs D3’s `scaleBand`, `scaleLinear`, `scaleOrdinal`, `axisBottom`, and `axisLeft` APIs to construct the axes and color encoding.
