Я следую этому учебнику, чтобы сделать карту хороплета в .D3.
У меня есть файл topoJson, который показывает окрестности Сан-Франциско.
Вот пример:

Я пытался сделать это с помощью этой команды:
topojson -o understandSF.json -e understandSFdata.csv --id-property=nhood,nhood -- SFtopojson.json
Я обнаружил, что topojson не является исполняемым.Как объединить CSV с файлом topoJSON?
