I have a csv table, with data in this format: "name","country". Country code is in the same format as the world map SHP file attribute table (both are in the ISO standard). I learned how to join the tables together, but I want to colorize countries based on how many people are from each country.
In this case Latvia should be darker than the two other countries (because two people are from LVA). I know how to colorize things based on a number that's bigger than other numbers, but how to achieve it without the numbers in the table? I only have raw list of names. Is this possible with Qgis only?
