Feature Request: Graphical representation of spending in different Expenses Category

[anjalirai0]

I think there should be a feature added under Expenses menu option which shows graphical representation (pie chart, line graphs) which shows my expenses trend in different categories (rent, shopping, travel etc.).
This would help me analysing the my expenditure more effectively, as the required data will be available in single screen.
Please consider, or if anyone have better idea on similar concept then do share
