Introduction to Data-Driven Shapes in D3.js

Introduction to Data-Driven Shapes in D3.js

This article will introduce some common shapes in D3 — including rectangles, circles, ellipses, lines and text — whose size will be based on numbers in the Fibonacci Sequence.

As a devout python fan, I’ve regrettably shied away from exploring many data visualization tools that are beyond the scope of libraries like Matplotlib, Seaborn, and Plotly. While perusing the diverse capabilities of D3.js in this visualization gallery, however, I was definitely excited to dip my toes in the water.

D3 is a JavaScript library that supports highly customizable and interactive web-based data visualizations. It’s short for “Data Driven Documents,” and it allows developers to create and manipulate web documents based on data. Having some prior familiarity with HTML, CSS and JavaScript will make it easier to get started with D3, but making simple shapes is possible with just the bare basics. This article will introduce some common shapes in D3 — including rectangles, circles, ellipses, lines and text — whose size will be based on numbers in the Fibonacci Sequence. These are just a sample of the many types of shapes that can be easily generated with D3 code.

What You’ll Need

To start making visualizations in D3, you will need a text editor, such as Atom, to edit your code. You’ll also want to copy the contents of the latest version of D3.js and paste them into a .js file in your text editor. In addition to the D3 file, you’ll need the following:

  • An HTML file to reference CSS and JavaScript documents and format the structure of the webpage
  • CSS file to format the webpage’s contents
  • JavaScript file for your D3 code

We’ll now take a closer look at the contents of each of these files.

Data Types In JavaScript

JavaScript data types are kept easy. While JavaScript data types are mostly similar to other programming languages; some of its data types can be unique. Here, we’ll outline the data types of JavaScript.

Introduction With Basic JavaScript

Introduction With Basic JavaScript - Unlike most programming languages, the JavaScript language has no concept of input or output. It is designed to run as a scripting language in a host environment, and it is up to the host environment to provide mechanisms for communicating with the outside world.
