This visualization displays actual rainfall in India for July, August, and September across the years 2001–2016, using overlapping semi-transparent area charts in orange, red, and green. It loads the data via `d3.csv` from a GitHub Gist, filters the years, and constructs the areas with `d3.area()`. The SVG rendering uses `d3.scaleLinear` for axes and `d3.axisBottom`/`d3.axisLeft` for ticks, with a custom legend and axis labels. The data source is a CSV file containing actual monthly rainfall measurements.
