This D3.js v7 visualization maps the locations of public and private universities across Texas using ZIP codes, with blue and red markers distinguishing institution types. It renders an SVG map of Texas via d3.geoPath and topojson.v3, plotting university coordinates with circle markers. Hover tooltips display each university’s name, city, and ZIP code, while permanent labels identify institutions directly on the map. The visualization uses hard-coded latitude and longitude coordinates from the included dataset, with mouseover and mouseout event handlers controlling tooltip visibility and marker emphasis.
