Calendar View v4
A calendar view displays the daily opening-to-closing price change of the Dow Jones Industrial Average as a heatmap, with each day’s percentage change mapped to an eleven-class RdYlGn color scale from Cynthia Brewer. Data from a CSV file is processed using `d3.nest` and `d3.rollup` to compute the daily change, which then colors each cell. The layout arranges days into weeks, months, and years, with SVG rectangles and paths rendered via D3 v4 APIs like `d3.timeDays`, `d3.timeWeek`, and `d3.scaleQuantize`.

This example demonstrates loading of CSV data, which is then quantized into a diverging color scale. The values are visualized as colored cells per day. Days are arranged into columns by week, then grouped by month and years. Colors by Cynthia Brewer. Layout inspired by Rick Wicklin and Robert Allison. Dow Jones historical data copyright Yahoo!
