The lesson
Publish your own data as a dated argument with claim-style chart titles, not as a dashboard.
The page is titled 'Cracks in the AI Thesis Part 3', opens with 'Dear Colleagues' and a short list of extras, then runs five charts. Titles state the point, for example 'AI spend is flat as usage rises' and 'Two straight months of no growth in token spend'. Each chart has a 'Copy embed code' link.
This depends on a real proprietary data set, so don't dress up public numbers as if they were yours. Keep the claim-as-title habit and the short opening note.
