Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities. Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined.

Before you begin, you’ll need a CSV with column headings on the first row. The CSV must have a column with the heading lat and another column with the heading lon . These columns should contain geographic coordinates in degrees. If your CSV contains place names or addresses instead of lat/lon coordinates, you can geocode that data so it works in TileMill.
You can prepare your own CSV or you can use earthquake data from the USGS for practice. Start TileMill and click on the Add project button on the main screen. Enter a name for your project and click Add . Click on the new project to open it. To add a CSV layer, click Add layer . Enter earthquakes in the ID field. Enter the URL into the Datasource field. Click the Save & Style button. Preview the result in the map preview pane. Mission complete!
