Retail Learns a Few Tricks from E-commerce

E-commerce has covered a lot of ground in analyzing and predicting buyer intent using web analytics to track user behavior on websites. However, retail still has a long way to catch up with its online counterpart. In a recent blog post on HBR, we get a glimpse of the future of retail in the work done at Prism Skylabs. They use a retail store’s security cameras to gather location-based data on its customers, and allows the store owner to plan product placement accordingly. They have a neat dashboard, which presents data in the right context.

The right way to show visualizations to a CXO

Alberto Cairo on Data Visualization

In his recent talk ‘It’s more complicated than that’, Alberto Cairo, author of ‘The Functional Art’ lays down some time-tested ground rules for data visualization.

Cairo is one of the influential thinkers in data visualization today, and you’ll get a lot of food for thought from his talk. Oh, and his spanish accent makes the talk even more lively.
