Researchers based in Oxford assemble long time series on poverty, health, energy, food and emissions, then publish each one as an interactive chart with the underlying figures downloadable. Charts switch between map, line and table views, and every source is named.
The download button sitting on every single chart is the quiet promise here: you can check the claim rather than take the picture on trust.
