It would be great to have some additional chart options when building dashboards, as a User sometimes you just need to see the specifics.
Donut pie chart - is already used at the record view intelligence dashboard, that would be a great addition to the Dashboard/report chart options
Gauge Chart - Gauge is used to show progress towards a goal.
Metric Chart - Metrics are used to show a single number like a grand total from a report with a label specified.
Thanks
