eBay, the world’s largest online auction place, recorded over a million transactions on Black Friday which is probably one of the busiest and most hectic shopping days of the year in US.

Now if you ever wondered what a Black Friday looks like on eBay (1 million transactions in less than 24 hours or around 12 transactions per second), check this interesting heat map on Facebook that captures all the buying-selling activity on eBay across the US on Black Friday.

What happens on a Black Friday

The areas with lower transactions during Black Friday appear in yellow while those with the highest number of total transactions on eBay appear in red.

The application has been developed by eBay using Virtual Earth so you can zoom in or out using the slider or hold the mouse button to pan around the heat map.

And here’s a non-interactive screencast video of the same heat-map visualization of US-based buyer and seller transactions that happened on eBay on Black Friday, 2009.
