Steps

1. Creating a CartoDB account

• Go to https://cartodb.com
• Find and click the "Sign Up" button
• The easiest option is to sign up with your Google account
• Once you have signed in, you will see the dashboard without any created maps

2. Downloading the data

• Go to http://gis.broward.org/GISData.htm
• Click on the "City Boundaries" link to download the zip file
• Alternatively, the zip file can be downloaded directly at http://gis.broward.org/GISData/Zipfiles/cities.zip or from here.
• The zip file contains shapefiles for the city boundaries. It doesn't have to be unzipped, but the contents in it are:

3. Creating a new CartoDB map

• On the CartoDB dashboard, click "New Map"
• Choose to "Connect dataset", then ensure "Data file" is selected, then click "Browse"

4. Uploading the data

• Select the zip file downloaded earlier
• Click "Connect Dataset" to upload the zip file. It is optional to "Let CartoDB automatically guess the data type and content".
• Wait a minute for the dataset to be uploaded. Once finished the dashboard will show the created map

5. Viewing the map

• Click on the map to view it. An initial map is shown.
• Click on the "Data View" tab to see the raw data of each city

6. Use default visualizations

• Go back to the "Map View" and click the "wizards" menu
• Select "Category" from the options and "cityname" as the "Column"
• Click on an empty area to hide the wizards menu then click to zoom out the map to show Broward county

7. Changing the styles

• Click on the "CSS" icon to open the CartoCSS editor. As we can see, default styles have been created by the Category wizard based on the "cityname".
• Replace the content with your own styles. For example, use the following styles. Note that '#cities9999' could be replaced by the actual dataset name if that is not the default 'cities' name.
