My Google Map
This interactive map visualizes H1B petition data across U.S. cities, with circles colored by year using a sequential YlGnBu scale. The map uses React and D3.js, with SVG rendering through `geoPath` and `geoAlbers` projections. A color legend allows hovering to highlight specific years, fading non-matching points. Geographic boundaries come from the US-Atlas TopoJSON, while city coordinates and petition years load from a CSV file.
