Since 2000, the Hewlett Foundation has made over 7,000 grants summing $3.86 billion, to support communities around the world. Periscopic broke it down by area and amount. Each section is a heat map with years on the horizontal and amount on the vertical. The darker the shade of green, the more grants given that year for the corresponding amount. Click on a rectangle, and you can see the details of any individual grant. [Thanks, Kim]
