I'm currently grappling with a JavaScript code and trying to make sense of it.
For the entire code, please visit this codepen site.
I've been on the hunt for where exactly the variable d3 is defined.
This particular variable plays a crucial role in multiple sections of the code, such as here:
let svg = d3.select('.chart-wrapper').append('svg')If anyone could shed some light on the origin of this variable, I would greatly appreciate it.
The primary object in the D3.js library is known as d3.
D3.js serves as a powerful JavaScript tool for manipulating documents based on data. It allows users to create dynamic visualizations using HTML, SVG, and CSS. By adhering to web standards, D3 provides access to advanced browser features while avoiding dependency on proprietary frameworks. Its blend of visualization elements and a data-centric approach to DOM manipulation sets it apart.
