Final Project - Ian Coolidge
This interactive map visualizes U.S. presidential election results from 1976 to 2020, allowing users to explore state-level winners, vote counts, and electoral college totals via a dropdown menu and hover tooltips. A custom mode lets users cycle state control by clicking, and right-clicking opens a multi-line chart tracking Democratic and Republican votes over time for that state. The visualization uses D3.js with `d3.geoPath` and TopoJSON for the map, alongside data from the MIT Election Lab dataset.
