A slider lets viewers scrub through the opening dates of Walmart stores across the United States, revealing the retailer's geographic expansion over time on a map of the country. The map uses `d3.geo.albers` for projection and `d3.geo.path` to render state boundaries from TopoJSON. Points marking each store location are driven by a `d3.svg.brush` slider, with a play button to animate the sequence. The data comes from a TSV file listing each store's coordinates and opening date.
