This week at the BUILD conference, Microsoft announced that Power BI custom visuals will soon be available as charts with Excel. You'll be able to choose a range of data within an Excel workbook, and pass those data to one of the built-in Power BI custom visuals, or one you've created yourself using the API .
Since you can create Power BI custom visuals using R , that means you'll be able to design a custom R-based chart, and make it available to people using Excel — even if they don't know how to use R themselves. There also many pre-defined custom visuals available , including some familiar R charts like decision trees , calendar heatmaps , and hexbin scatterplots .
For more details on how you'll be able to use custom R visuals in Excel, check out the blog post linked below.
