Startup Idea : A Search History Timeline Generator

I have been saving my Google web search history for many years now, but there is no convenient way to navigate it beyond the clickable calendars by year and then paging through all the searches for each one. I would like to see something like the bar graphs they show for your most popular searches, but more like a timeline that can create a visualization of your searches over time. This would be cool because it would lay out a clearer picture of what things you were interested in at different points in the past and would indicate what was going on in your life as well. I don't know how possible this is considering it's a Google service. I don't know what developers can and can't do with this idea, so feel free to educate me on that if I'm being stupid here.
