From Bamboo Solutions web page:
The SharePoint Project Portfolio Dashboard gives you a simple view of the progress, health, and risk level of a single project, or the projects in your entire project portfolio.
I created a Team Site, deleted everything from the front page, and added the Project Portofolio Dashboard.
What I got was rather messy:
So I created a new Web Part Page to give the Dashboard more real estate on the page:
The Dashboard consists of several charts.
A Gant View:
Active Projects Health:

Overall Health of Active Projects:
At Risk Projects:
Planned vs. Actual Effort for Active Projects:
Types of Active Projects:
Phases of Active Projects:
Active Project Budgets:
The data the Web Part builds on lives in the Portfolio DashBoard List:
Each list item consist of a lot of information:
And the Web Part itself has a lot of configuration options!
Each of these categories have a lot of options – this was very confusing. My opinion is that they should have divided this up into several Web Parts – instead they’re using the term Widget about each of the areas of the Web Part.
