Feature request: Add visual chart of counts over time

[Lowell-Syncrety]

I'd love to see a visual chart of a counter with counts over time. For example, looks like over the last hour the number of cars I've counted passing the house shows that near the top of the hour there were far more than at the remainder of the hour.
I see the new feature that shows the timestamp of the latest count, so if those are tallied on a chart that'd be cool.
