This table visualization displays monthly price data for DPC websites, with columns representing the most recent twelve months and rows sorted alphabetically by website name. Cell background colors encode percentage changes using a diverging scale from red through orange to green, calculated from quartile thresholds of all change values. The page includes a frequency menu built with a custom d3.menu component, though it only logs selection changes to the console. The implementation uses d3.csv for data loading, d3.group for aggregation, and d3.select for DOM manipulation.
