Workfront Integration with Visualization Tools (Microsoft Power BI and Tableau)

From Power BI, you can export to PowerPoint, or even better...From PowerBI. Click File, Embed Report >> Website or Portal. This will provide an embed link URL. From within Workfront, you can setup a dashboard, and add a URL through the Add External Link. You can then copy and paste the PowerBI Embed link. There may be a prompt to login to PowerBi, but once you do, the chart will show on the dashboard. 

I tried using the embed link option and added it to a dashboard as an external link. It works fine, though you will get a login prompt first.

Steven's embed workaround works well for getting Power BI charts into Workfront. You'll still need a decent grasp of Power BI itself to build useful visualizations. I took power bi training uk and it helped me a lot with that. The course covers Power Query, DAX, and dashboards, so you can then just focus on the embed step.
