This fork of a radar chart displays monthly average temperature anomalies for Massachusetts from 1895 to 1908. The visualization combines a focus chart with a context chart, allowing users to explore yearly patterns through a dropdown menu that selects specific years. The code uses React for the UI components, D3.js for data parsing and visualization, and d3.csv to load the Temperature.csv dataset. The chart renders temperature anomaly values across months, with an interactive menu providing year selection.
