    <p>I am trying to create a choropleth map in Google Maps to visualize some international country-level statistics. It will be an add-on to an existing Google Maps application.</p> <p>I searched around and found these potential solutions:</p> <ul> <li><strong><a href="http://cartographer.visualmotive.com/" rel="nofollow">Cartographer.js</a></strong> has the ability to overlay vector-based choropleth maps directly on Google Maps. However, it only supports US states.</li> <li><strong><a href="https://www.google.com/fusiontables" rel="nofollow">Fusion Tables</a></strong> can also be used to create choropleth overlays (<a href="https://www.google.com/fusiontables/embedviz?viz=MAP&amp;q=select+col1+from+1YHQBsKPsnytQt6n2zy_ks5r8RFBjPqnODxvFlL8&amp;h=false&amp;lat=17.62365070527682&amp;lng=-20.834000000000035&amp;z=3&amp;t=1&amp;l=col1" rel="nofollow">example</a>). However, this adds complexity because data is maintained outside of my database. I also have to obtain and maintain country boundaries data.</li> <li><strong><a href="https://developers.google.com/maps/documentation/business/demographics" rel="nofollow">Demographics Layer</a></strong> would have been perfect, but it is for Business customers only. Plus, it is limited to US geography.</li> </ul> <p><em>So my question is...</em> Is there a better way to do this in Google Maps JavaScript v3?</p> <p>P.S. I just came across <strong><a href="http://jvectormap.com/" rel="nofollow">jVectorMap</a></strong>. It looks promising (<a href="http://jvectormap.com/examples/world-gdp/" rel="nofollow">example</a>), except that it is just a standalone map. It would be nice if I can somehow combine the jVectorMap functionality with the Google Maps interface.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
