In my little project I have a CSV with more rows than I can count, and I am trying to find a tool that can do the following:
- Plot each record on a map using their lat lon coordinates, interactively so a mouse hover can display some metadata.
- Each marker is coloured based on the categorical value of one of the columns.
- Be able select a subset by area (such as in QGIS), and change their categorical value.
- Save these changes back into the original CSV.
