This area chart visualizes IPL team performance by plotting points scored against year, with each team represented as a filled area using custom colors. The chart groups data by team using `d3.group` and renders areas with `d3.area`, while tooltips on hover reveal team, year, and points. It leverages D3 v7 scales (`scaleLinear`, `scaleOrdinal`), axes, and a legend, loading CSV data from a gist. The visualization includes SVG rendering and interactive tooltip transitions, with animation implied through hover interactions.
