The lesson
Title each chart with the claim it proves, and open the post with the paradox in one sentence.
The title is "How GPU Prices Can Double While AI Gets Cheaper", followed by an "IN SHORT" box. The first chart is titled "B200 rental prices doubled to $8.08 per GPU-hour in nine months"; the second, "Rates & tech valuations have decoupled". A numbered source list and a newsletter signup follow.
Don't copy the GPU topic or the exact figures. Keep the claim-as-title chart habit and the short summary box, and make sure your chart's timeframe matches your text.
