How to Make an Interactive Map of Geographic Paths
With latitude and longitude coordinates, there are a number of ways to map geographic data using D3.js and Leaflet.
This tutorial shows several ways of visualizing geographic point data using JavaScript. You’ll visualize the data in a web browser using JavaScript libraries D3 and Leaflet and learn how to:
- Visualize all the point data
- Visualize the running routes by joining the points
- Use opacity to get a sense of the most popular routes
- Animate the points along the routes
- Show the routes on a interactive map
