How I Created 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!

How to Build Box Plot Using JavaScript: Visualizing World Happiness

September 22nd, 2020 by Wayde Herman

A box plot visualizing world happiness report data, the cover image for a guide on how to build interactive box plots with JavaScript HTML5Data visualization is an important and sometimes undervalued tool in a data scientist’s toolkit. It allows us to gain an understanding and intuition about the data, through exploratory data analysis, which influences preprocessing, feature engineering, and the correct machine learning algorithm choice. It also helps to better evaluate models and even allows you to spot areas in the data where models could have poor performance.

Taking data visualization one step further by adding interactivity is even more advantageous. By adding interactive elements to your visualizations you create a more engaging experience. This in turn makes a user ‘explore’ visualizations instead of just reading them!

In this tutorial, I will be covering how to build an interactive data visualization, specifically a box plot as an example, using JavaScript and a charting library. I will begin by first briefly covering the basics of box plots before going through the steps of building one and then finally using the technique in a fun example to investigate the distribution of happiness between the different regions of the planet in an attempt to answer the question: ‘Where should you live to be happier?’.

June 25th, 2020 by AnyChart Team

Visualizing COVID-19 Pandemic Data for Austria Using AnyChart JS ChartsThe COVID-19 pandemic persists as a global emergency, and we continue to support initiatives that contribute to tackling the coronavirus crisis. Specifically, we allow COVID-19 analytics projects to use our data visualization tools for free under a non-profit license.

You already know about StopCorona, a COVID tracker by Diffco, which is one such resource. Today, we want to meet you with another noteworthy project using AnyChart to visualize the pandemic statistics — iConcepts SARS-CoV-2 Stats. Created by Austrian part-time web developer Juergen Hoefer and featured on the official Open Data Austria portal, it shows the COVID-19 statistics for Austria (and worldwide) from different perspectives, in countless interactive charts powered by our JavaScript (HTML5) charting library.

We asked Juergen a few questions to learn more about this project and his experience visualizing COVID-19 pandemic data with the help of AnyChart. Read the answers and take a glance at several quick chart examples from his website. (Stack: HTML/CSV.)

Building JavaScript Scatter Plot Module

May 27th, 2020 by Wayde Herman

Tutorial title image of a JavaScript Scatter Plot module (scatter chart)Scatter plots are a great way to visualize data. Data is represented as points on a Cartesian plane where the x and y coordinate of each point represents a variable. These charts let you investigate the relationship between two variables, detect outliers in the data set as well as detect trends. They are one of the most commonly used data visualization techniques and are a must have for your data visualization arsenal!

In this tutorial, I will teach you how to build your very own interactive scatter plot charts using JavaScript.

Ever wondered whether the population of the United States of America were dog people? Well, you’re about to find out! To help you learn more about building scatter plots I will be using the Cat vs Dog Popularity in US dataset. This dataset contains the percentage of homes with dogs and cats for each US state.
