Power Map is an Excel add-in which provides a powerful set of tools to help you in visualize and gain insight into large sets of data that have a geo-coded component. It can produce 3D visualizations by plotting up to a million data points in the form of column, heat, and bubble maps on top of a Bing map. If the data is time-stamped, it can also produce interactive views that display how the data changes over space and time.
