This visualization presents a tabular heatmap of price changes across various DPC websites, organized by website name in rows and the most recent 12 year-month periods in columns. Each cell displays a numeric change value, with background colors encoding the magnitude of change: reds indicate lower values, oranges mark zero, and greens represent higher values, based on quartile thresholds. The table is built using D3 v7, loading CSV data with `d3.csv`, grouping rows with `d3.group`, and sorting year-month pairs in descending order.
