Metropolitan Unemployment
This visualization shows the distribution of unemployment rates across 380 U.S. metropolitan areas from January 2000 to December 2012. Using a time-series heatmap, it displays monthly unemployment rate bins as colored rectangles, with darker purple indicating higher numbers of areas within a given rate range. The code uses D3 v3’s `d3.time.scale`, `d3.svg.axis`, and `d3.interpolateLab` for color interpolation. Data from the Bureau of Labor Statistics is loaded via `d3.json` and rendered as SVG rectangles.

This visualization shows the distribution of unemployment for 380 U.S. metropolitan areas from January 2000 to December 2012. I’m currently weighting each area equally, but it would probably be better to weight areas by the size of the civilian labor force. Thanks to Kevin Quealy for suggesting this dataset, which was the basis for his earlier graphic!
