Web Maps

Before we dive into CartoDB, let's talk a little bit about web maps

Step 1: Importing a Dataset and Creating a Map

Import the files subwaystations and starbucks_locations into your Carto account by drag and dropping them into the Dataset Dashboard, or pasting the URL into the Import dialogue

show little boxes for links to the files

Show how easy is to import files into CARTO! Explain the viewer the wide diversity of geodata supported in CARTO during the importing.
