Information Visualization of Browser History

Hello! Sorry I didn't answer earlier! The interface is very confusing! My mistake! You have to click on a graph icon next to the extension name in the top menu, so it opens a menu with options. There are three options Bubble Chart of Most visited Domains, Graph Chart Of Visited Urls And Referers, Chart of Visit Frequency. Unfortunately, the last two stopped working, I'll have to fix them. But the Bubble Chart of Most visited Domains still works, give it a try and tell me what you think! Many hugs!
