This map of NBA team locations uses D3 v5 projections with `geoAlbers` to render U.S. state boundaries and team positions. The code plots each team as a large gray circle at its latitude and longitude, with the team abbreviation as text labels. It retrieves data from a CSV URL and TopoJSON from the us-atlas package, combining React state hooks with D3's `geoPath` and `geoGraticule` APIs. The visualization also includes state interiors and graticule lines for geographic context, using SVG rendering within a React component.
