A choropleth map of New York State displays the percentage of adults aged 25 and older with a bachelor’s degree or higher, using a yellow-green sequential color scale for each county. The visualization is built with React and D3, using the `geoMercator` projection and `geoPath` to render filtered county and state borders from TopoJSON. The USDA Economic Research Service dataset for 2010–2014 provides county-level education values, with interactive tooltips showing details on hover.
