Brushing+Linking, How Are My Tweets Doing?
Show both the graph and the table. Selecting a tweet, or group of tweets, in the table would highlight those tweets on the graph. This makes it easy to select exactly which tweets I'm interested in (especially in a group of tweets whose impressions/retweets are all similar), and doesn't require the construction of any additional views.
If you want more cool ideas you should hire me.
