Building Column Charts with JavaScript

December 29th, 2022 by Shachee Swadia

Building Column Charts with JavaScriptWith data everywhere around, we should know how to graphically represent it to better (and faster) understand what it tells us. One of the most common data visualization techniques is column charts, and I want to show you how you can easily create interactive ones using JavaScript.

A column chart is a simple, yet powerful way to display data when you need to compare values. From this tutorial, you will learn to make its different variations — basic single-series, multi-series, stacked, and 100% stacked column graphs — and apply effective customizations in a few more lines of JS code.

As a cricket fan, I thoroughly watched the ICC Men’s T20 World Cup held last month in Australia. I decided to use some data related to the championship for illustrative visualizations. JavaScript column charts built throughout this tutorial will let us look into the batting statistics, and more precisely, the number of runs scored by the top 10 batsmen at the tournament. Let’s have fun learning!

How to Create Word Tree Using JavaScript

October 14th, 2022 by Awan Shrestha

A word tree chart in JavaScriptIt is a pure fact that a graphical or pictorial representation of data, known as a data visualization, conveys information faster than raw data in arrays, spreadsheets, or dense reports. Charts make data easier to understand, which further helps to quickly develop valuable insights. Interesting, right? Now, let’s have a look at one chart type called a word tree and see how to build it with ease.

A word tree is a data visualization form designed to show multiple parallel sequences of words (or phrases) as they appear in a text. Analyzing texts becomes easier with word trees as they display, by means of a branching structure, how selected words are connected to others.

In this tutorial, I will walk you through the process of creating a beautiful word tree chart with JavaScript (HTML5). The text being visualized will be the famous speech “I Have a Dream” by minister and civil rights activist Martin Luther King Jr. Each step will be explained in detail, and you’ll see everything is pretty simple. Sit tight and enjoy the learning!
