Building a Marimekko Chart with JavaScript

December 22nd, 2020 by Dilhani Withanage

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!
