I want to build a Choropleth map, from a specific region (in my case Portugal) with D3.JS and while searching for tutorials and support, I have found this website.
Following the procedure, I have drawn the visualization that I want to build in a piece of paper.
Then I have downloaded a map from Eurostat and got the information from the shape that I want to use, by uploading the file in mapshapper.
Considering that I know which information I want to extract from the GeoJSON file, the tutorial suggests the usage of OGR2OGR. In order to do that, I have installed the GDAL package on Anaconda, but I can't extract the map information.
