Hi Jorge,
First of all, thank you for all your ideas!!
We are translating all strings to English, our first idea is was orient the Spain visualization to Spanish speakers only.
Related with choropleth maps we did not know about that. In order to solve this and create a better representation, we will probably calculate a KPI with the ratio between confirmed cases and the total population outside elastic and then insert that values.
In future days I will edit the main post with the news.
