This interactive choropleth map displays weekly avocado sales volumes across US states, with a slider beneath the map letting users select any week of 2017. State boundaries are rendered using `d3.geoPath` with a `geoAlbersUsa` projection, while translucent teal circles sized by `scaleSqrt` exaggerate total sales per state. A timescale brush updates the map by filtering CSV data on the selected date. The code combines TopoJSON for state geometries, D3 v5, and an SVG rendering approach with zoom support.
