It would be nice if the visualization reflected the information you've shared here (including both the absolutes and the amount of change). Then it wouldn't feel misleading and you would not need to write explainer comments on HN.
The absolutes are in a bar chart in the framework part of the survey that makes the absolute usage from the responses very clear. The chart Zack took issue with is from the editorial part of the survey where we found the biggest news in the framework section to be the growth and satisfaction for Astro.
