Making a JS Dot Density Map to Visualize Shipping Ports Across the Globe
Summary
The final two lines of code are setting the container to reference the previously added HTML block element and drawing the map. You may want to make your graphic aesthetically better, to highlight a particularly interesting aspect of the data visualization, or to add some functionality to improve the information being shown. I will show you how to customize the JS dot density map in the following ways: • Indicate the number of outflows at each shipping port with a color scale. Indicate the number of outflows at each port with a color scale I wanted to show more information in the visualization without adding too much complexity. Check out the Move and Zoom API documentation if you want to set up any other interactive behavior to let the viewer dig into the data displayed on the map.
