Add mileage over time graph to Car Insights#147

The insight tab gives a breakdown of cost only, but it would be nice to see other simple graphs and ways to visualise things like milage over time, pulled from your history entries

Hi @Biggsy1 more information coming soon!

We will indeed have a mileage tracker which will be powered by history file entries and there also more to come in addition to that as well! Including cost of ownership and maybe if some deals go well, some pretty advanced valuation tooling!

Pleased to know you’ve been finding the new feature useful!

Best,
Jeremy
