Make sense of a chart or table in plain words

Explain this chart or table.

Description or paste: [details]
My question: [what I need to know]
Source if known: [optional]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. What it shows in plain words.
2. The main takeaway.
3. What it does not show.
4. A caution about scale or missing context if relevant.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, steps or official URLs you're not sure of. UK English.
