I am very new to CartoDB. I have a set of tables uploaded and am able to create the visualization and it works fine in the CartoDB web site.
However, I want to use a simple basemap and then add my layer from the SQL query. But I cannot seem to find a simple example of how to do this in an HTML web page.
I found an example that used a leflet map (not sure what that is) but it does not display the basemap behind the data, just displays blank white.
