How to read the stock market heatmap

StockMap's home page draws the whole US stock market as one heatmap. Each tile is a company, grouped by sector, sized by its market value and coloured by how far its price moved. Choose a different period to see the same map for the last month instead of today.

What you see at the end: The map recoloured for one month
