Create a Flow Map with JavaScript: Step-by-Step Tutorial

▤ Summary

Next, we’ll include the necessary scripts in the head section of our HTML file to develop the JS flow map. The data source for this visualization is the Ministry of External Affairs, India, which provides information on the number of Indian students studying abroad. The table below shows the list of the selected countries, along with the total number of Indian students studying there and the coordinates of their respective capital cities. In the upcoming steps, we will be making some quick and simple modifications to the code to add more features and customization options to the flow map. We can modify the Javascrit flow mapping code where we created the series connector and use the and functions to apply the gradient color.
