This visualization displays avocado sales volume across U.S. states for the week of January 15, 2017. A choropleth map colors states with recorded sales in pink and those without in gray, while proportional circles over each state’s centroid use a square-root scale to represent total sales volume. The map uses an Albers equal-area projection via `d3.geoPath` and `geoAlbersUsa`, with data from a CSV joined to TopoJSON state boundaries. Circles and state paths are rendered as SVG, with tooltips showing state names and sales figures.
