Building JS Resource Gantt Chart to Visualize Tokyo 2020 Paralympic Schedule

August 17th, 2021 by Shachee Swadia

A Mac screen with an interactive JavaScript Resource Gantt chart visualizing the Tokyo 2020 Paralympic schedule by venueSmart resource allocation is a must to achieve a high level of operational efficiency. Aiming to ensure it, project management professionals commonly rely on a special form of data visualization called a Resource Gantt chart. Creating graphics like this may seem daunting at first sight. But I am here to show you an easy way to build Resource Gantt charts with JS using a compelling, topical example.

Resource Gantt charts, also known as simply Resource charts, consist of bars oriented along the horizontal axis. Each bar visualizes a resource used by an activity, with the length representing the duration while that resource is occupied by that activity. The left and right edges of the bars display the start and end times. The resources, or event labels, are listed on the left. The dates and times are shown in the header.

Tokyo 2020 Paralympic Games are just around the corner. So, I decided to visualize their sports program by venue. Follow along with this stepwise tutorial and you will learn how to create a cool JavaScript Resource Gantt chart visualizing the Tokyo 2020 Paralympic schedule!

How to Create a Line Chart with JavaScript

July 28th, 2021 by Shachee Swadia

A JavaScript-based multi-series line chart on a laptop screenA line chart is one of the basic and most commonly used techniques of data visualization. Such graphics are known to provide an informative look at the change of one or several variables over time. Right now, I’ll explain how to easily create a cool interactive line chart using JavaScript! The process will be demonstrated with the help of compelling examples that you can play with afterwards to hone your new data visualization development skills.

To make the article especially thrilling for you to read and learn from, I decided to showcase a practical application of a line chart to real-world data. The month of June was celebrated as Pride Month, and I thought it would be great to see how attitudes toward LGBT people have changed over the recent years. Then I found interesting public opinion data from the General Social Survey (GSS), a project of the National Opinion Research Center (NORC) at the University of Chicago, which appeared to be a good fit, and took part of it to visualize in this guide.

So, follow along with the tutorial and you will also be able to explore the shifts in acceptance of same-sex relationships in the United States over the last two decades! We will create a single-series JS line chart first, representing the general trend, and then a multi-series JS line chart to visualize a breakdown by age group.

All aboard!

A Waterfall Chart with JSDo you want to know how to easily add a waterfall chart to a web page or application using JavaScript? This tutorial will make sure you’re prepared to confidently deal with that sort of interactive data visualization development!

Waterfall charts illuminate how a starting value turns into a final value over a sequence of intermediate additions (positive values) and subtractions (negative values). These additions and subtractions can be time-based or represent categories such as multiple income sources and expenditures. In finance, a waterfall chart is often called a bridge; you may have also heard it referred to as a cascade, Mario, or flying bricks chart.

To see waterfall charts in action and learn how to build them with JavaScript (HTML5), we need some interesting real-world data to visualize. In this tutorial, let’s look at the 2020 income statement for Alphabet Inc. (GOOGL), the parent company of Google.

Hence, be with me to reach our target step by step, so in the end, you’ll see how a lot of numbers can be made sense of with real ease when illustrated as a beautiful, interactive, JS waterfall chart. All aboard!

A Marimekko Chart built with JavaScript displayed on a laptop screenWould you like to know how to easily create an interactive Marimekko chart for HTML5 based apps and Web pages using JavaScript? If yes, you are on the best path to learning this.

Also known as Mekko charts and market maps, Marimekko charts display numerical values that vary from 0% to 100% in its Y-axis. The most exciting part lies in their X-axis, which indicates the sum of values within categories. Each category’s width along the X-axis portraits the whole category’s contribution to a total of all data. In simple words, this is a type of a stacked chart that visualizes categorical data. Still, both the Y and X axes vary in a percentage scale by determining each segment’s width and height.

Are you a smartphone enthusiast and interested to look at the global smartphone shipments in 2019 by quarter and by vendor? Then especially follow the present tutorial as we are to visualize this market data in an elegant Marimekko diagram using simple JS chart coding techniques.

How I Created a Sunburst Chart Using JavaScript to Visualize COVID-19 Data

December 8th, 2020 by Shachee Swadia

A tutorial on how to create a sunburst chart using JavaScript to visualize COVID-19 dataAlmost recovered from COVID-19 myself these days, I decided to explore how the world is currently doing, during the pandemic. So I created a sunburst chart to see at a glance what continents and countries are more (and less) affected by the coronavirus than others. The process was quick and I thought someone could be interested to learn about how such data visualizations can be built in a pretty straightforward way, even with very little technical skills. So I also made a tutorial. And here I am — (1) sharing my interactive sunburst chart of COVID cases and (2) describing how I created it using JavaScript in a matter of minutes, step by step!

My JS sunburst chart provides an overview of the situation as of November 24, 2020, and also shows the global count, continent-wide data, and country-wise proportions for the current active COVID-19 cases and deaths. Scroll down to explore it by yourself and check out the tutorial along the way. Here is a sneak peek of the final chart to get you excited:

JavaScript Sunburst Chart to be created

This sunburst charting tutorial is mainly for beginners to data science. So before we get to business, let’s make sure we’re on the same page. I’ll explain what a sunburst chart is and how it works, to start with. Then I’ll show you how to create a cool and colorful interactive visualization like that with JavaScript (and you can do it even if you don’t know it too well). That’s the plan!
