Use Google Chart Tools to create dashboard components for the Customer Portal. Dashboard components are a great way to graphically represent salesforce.com data. However, even though reports are available to Customer Portal users, dashboards components are (sadly) not. We’d like to create one or a series of Visualforce components that could be used to mimic a salesforce.com dashboard.
First Place: $750
Second Place: $250
Use Google Chart Tools to create either a single Visualforce component or individual Visualforce components to display a pie chart, bar chart and table chart for Force.com data. Display all three charts on a Visualforce page to mimic a salesforce.com dashboard. Link each chart to a URL which could either be a report or another Visualforce page.
Be as creative as possible to make the Visualforce components flexible and reusable.
The components can use either a standard controller, custom controller or controller extension.
Must have adequate test coverage (75%+).
