MapChart

Nothing too fancy in terms of data, but perhaps a cool use case.

Uses Google Geomap chart to show a 'heat map' of revenue (Opp report, summarised by Opp.Account.BillingCountry, with sum of revenue)

Think it will require Country Picklist to be enabled in your org as that creates the country ISO codes in the background, which are then available when you retrieve the report via Analytics API.
