This interactive bar chart visualizes the mean attack stat for 18 Pokémon types across generations 1–6. Buttons let viewers reorder the bars alphabetically, by attack value, or by a derived attribute, using a reusable closure-style chart function with chainable getter/setters. The visualization loads CSV data via d3.csv and renders with D3 v7’s scaleBand, scaleLinear, and axis components in SVG, with bars rotated labels for readability.
