this is fun, but is this true? https://twitter.com/michael_nielsen/status/1241353597960343553

we built an app a while ago for our research project ( https://liris.cnrs.fr/mi2/ ) to understand space occupation in cities (e.g. how far you can go in X minutes or if you walk 5km)

it turns out to be quite useful to assess social distancing.. right now the app calculates distance using simple Voronoï models without any perspective / space limits

our focus was more on the app's reliability and to provide tools to analyze distances: #dataviz charts, table to export data, collaborative features, etc.
