The data is not easy to format. Why not suggest something like this? async function fromEurostat(query) { const result = await d3.json(query); const category = result.dimension.geo.category; return Object.keys(category.index).map((key) => ({ id: key, label: category.label[key], value: result.value[category.index[key]] })); } fromEurostat( "https://ec.europa.eu/eurostat/api/dissemination/statistics/1.0/data/reg_area3?format=JSON&unit=KM2&landuse=TOTAL&lang=EN&TIME=2025" ) Of course, this would need to be improved when there are several indicators or several years. But we want to retrieve the data formatted in this way.

Excellent suggestion, thanks! I agree that the API responses are not the most intuitive!

Are you planning to do something along these lines?

Unfortunately I am not involved in the API development, I'm just a consumer of it! I suggested something a while ago but they do not want to deviate from JSON-stat

Okay. I understand that it's too late to modify the API. But maybe we can write a nice function to format the data.

Yes, maybe it would be nice to have some examples here of formatting responses that contain multiple years and also an option to include a value's 'status' flag (e.g. 'estimated'). I will add them when I can!

In the meantime you can use the jsonstat-toolkit functions shown below!
