How to Create an Interactive Timeline Chart with JavaScript

June 17th, 2021 by Shachee Swadia

A laptop screen with an interactive JavaScript Timeline Chart of COVID-19 vaccine development built along this JS charting tutorialI think all of us have come across timelines somewhere or the other; as a means of conveying chronological information, the classic timeline is unmatched, both in the depth of information conveyed and the “cool” factor, when done with a deft creative touch. So, with that said, would you like to learn how to build a timeline chart using JavaScript that both looks great and is simple to create? (Of course, you do!) Follow along with me as I take you through the step-by-step breakdown for developing your own JS timeline with a practical example.

As the world continues to battle with COVID-19, the long-awaited good news is the development of vaccines across the globe. Here, I decided to build an interactive timeline that showcases the phases of Pfizer-BioNTech vaccine development in the United States. To add more contextual information, I also wanted to show approvals from other countries and some related facts, including the dates for the development of the 3 other vaccines approved for usage in the US.

April 20th, 2021 by Shachee Swadia

An interactive JavaScript Dot Density Map data visualization showing the distribution of shipping ports across the globeThe recent incident of the Suez Canal blockage caught my interest in shipping and prompted me to explore the various shipping ports around the globe. There are more than 850 ports in the world and to get an overall view of where these are located, I decided to plot them on a dot map, or dot density map, using JavaScript.

Building an interactive JS dot density map can seem like a daunting task. But let me assure you that it can be pretty straightforward. Right now, I will show how to make a fully functional dot map chart using a JavaScript library for data visualization.

COVID-19 Dashboard Tracker Using AnyChart JS Charts for Interactive Data VisualizationData visualization has played an important role during the COVID-19 pandemic, allowing governments, scientists, healthcare professionals, and the general public to better understand different aspects of the crisis. There are many illuminating projects all over the web that leverage charts and maps to effectively communicate what the coronavirus statistics have to say. Some of them are using our data visualization tools under a free license provided as part of the special initiative we announced last spring to support the global COVID-19 data analysis effort.

We told you about two examples of such projects earlier: StopCorona and iConcepts SARS-CoV-2 Stats. Now let us introduce you to another interesting resource — COVID-19 Dashboard Tracker by Maxime des Touches. Launched more than a year ago, while Maxime was yet a computer science student, it has turned from a simple online data table into a complex interactive data visualization project offering up-to-date insight into how the pandemic unfolds in France and worldwide.

Maxime kindly agreed to talk to us about his COVID-19 tracker, experience using AnyChart, and the pandemic in general. Check out our quick interview, glance at a few screenshots, and try his open-source dashboard by yourself. (Stack: HTML/jQuery/JSON.)

How to Build a Pareto Chart in JavaScript

February 16th, 2021 by Dilhani Withanage

Pareto chart created in JavaScript being shownCreating a Pareto chart with JavaScript for HTML5 apps and websites is not a complicated or hectic development process at all. Get hands-on experience with this tutorial and you will find data visualization in such a form joyful and exciting!

Before we start, let’s remember how Pareto charts look and what their purpose is, just to make sure we are on the same page. A Pareto chart, also a Pareto diagram, is a combination of vertical bars (columns) and a line graph. Columns are used to depict values and are displayed in descending order, left to right. The line in a Pareto chart shows the cumulative total in percentages. Such a visualization helps data scientists and analysts quickly identify the most important among a set of factors, i.e. those characterized by the largest values and therefore making the most significant contribution to the total across all the represented factors.

In this JS Pareto chart tutorial, we’ll be visualizing statistics for the leading causes of death in the United States in 2019 and find out what claimed the most American lives during that year according to official data.

Now let’s move to JavaScript charting, and more precisely, building an interactive Pareto chart using JS!

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!
