D3, or Data-Driven Documents, is a library of JavaScript that allows you to create interactive data visualizations. It’s widely used by data scientists, web developers, and many other individuals to create interactive visualizations. One of its most powerful features is the ability to read data from a CSV file and generate a SVG (Scalable Vector Graphics) representation of that data.
The beauty of D3 is that it’s very easy to get started. All you need is a web browser and some basic HTML and JavaScript knowledge. Once you’ve installed D3 and have a web page set up, you can begin creating SVG representations of your data.
In this tutorial, we’ll be using D3 to read from a CSV file and generate a SVG representation of the data. The data we’ll be working with is a simple CSV file containing a list of cities with their respective population. We’ll read each row of the CSV and create a circle for each city with its respective population as the radius of the circle.
Getting Started With D3
Before we can begin creating our SVG visualizations, we’ll need to install D3 and set up a web page. D3 is a library of JavaScript code, so you can install it using a package manager like npm or yarn. Once you’ve installed D3, you’ll need to create a web page to write your code in. You can do this with a simple text editor or an IDE like Visual Studio Code.
Once you’ve got your web page set up, you’ll need to include the D3 library in your page. This can be done with a simple
