JavaScript library to transform coordinates from one coordinate system to another, including datum transformations

Project mention: How to Build a Choropleth Map in JavaScript | dev.to | 2023-05-26

It is needed to link the required JS scripts in the section of the HTML page. These scripts include the Core and Geo Maps modules and the file that contains geodata for the world map, all of which are available on the CDN. I'll also use two more script files to connect the data to the choropleth map. One is the Data Adapter, which will help load the data, and the other is Proj4js, a JavaScript library that will transform the coordinates from one coordinate system to another so the data can be plotted on the map accurately.
