Why it spread
It spread because a data journalism account posted a Sankey chart on a topic with broad appeal, earning 429 likes, 148 reposts, 15 quotes, 102 saves, and 39,812 views, with an above average quote rate and a source line reaching the top quarter of accounts.
What worked
- The Sankey chart type is unusual for population rankings, which made the post stand out.
- The post is self labelling and highly polished, helping viewers understand the projection from 2025 to 2100 without extra explanation.
- The independent author and branded presentation gave the chart credibility and shareability.
What to borrow
We could use a Sankey or other unusual chart type to show flows or rankings in our own data, keep the design highly polished and self labelling, and include a clear source line to reach a similar audience.
Careful
Do not assume the same numbers will apply to our account, and do not over-read the missing typical likes or normal multiple, since those were not provided.
