Meagan Longoria has a checklist:
For more formal enterprise Power BI development, many people have a checklist to ensure data acquisition and data modeling quality and performance. Fewer people have a checklist for their data visualization. I’d like to offer some ideas for quality checks on the visual design of your Power BI report. I’ll update this list as I get feedback or new ideas.
Read on for the list, as it’s a good one. For the most part, these also apply to visuals created in other tools.
