Oil spills from tankers have fallen by more than 90% since the 1970s, In the 1970s, oil spills from tankers, container ships transporting oil, were common. Between 70 and 100 spills occurred per year. That’s one or two spills every week.
Why it spread
This post spread because it explains itself and hit a hot topic that week, reaching 12,113 views with 166 likes, 33 reposts, 3 quotes and 23 saves.
What worked
- The post explains itself, so readers grasp the more than 90% fall in tanker oil spills without extra context.
- It rides a hot topic that week, which helped a data-journalism account reach 12,113 views.
- The chart is a branded stacked bar with high self-labelling and a source line, and the text frames the drop from 70 to 100 spills per year as one or two spills every week.
What to borrow
We could pair a stacked bar with a plain-language framing that turns our own figures into a weekly or everyday comparison, and keep high self-labelling plus a source line.
Careful
Do not over-read the quote rate, which was below average, or assume the same framing will travel for every topic.
