Building an Elementor Heatmap Widget from scratch

In this step-by-step tutorial, we'll show you how to build a powerful heatmap widget using Elementor, OpenStreetMap, Leaflet, Leaflet heat, and Papa Parse.
With this widget, you'll be able to create stunning maps that display the distribution of data points in a visually engaging and interactive way. Whether you're looking to showcase the location of your store branches, visualize customer behaviour on your website, or display real-time traffic data, this heatmap widget can help you do it all.
Along the way, you'll learn how to work with OpenStreetMap data, use the leaflet and leaflet heat libraries to create interactive maps, and parse your data with Papa Parse.
By the end of this tutorial, you'll have a working heatmap widget that you can use on any Elementor-powered website to display data in a meaningful and engaging way. So, let's get started!
