Those of us who have been around a while know that mileage is effected by temp. They say a picture is worth a thousand words so I'm hoping you all in charge can add an option to display the temperature as a different colored line than the mpg in the database graphs.

This used to be a feature in the previous version, but unfortunately for individual cars it was very hard to see an association. There were simply too many variables. On the large scale—with every car in the data, perhaps an association would be obvious.
