How to Build 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!

Creating JavaScript Angular Gauge

February 3rd, 2021 by Shachee Swadia

Angular gauge in JavaScript on a laptop screen visualizing Grammys Record of the Year nominee songs popularity based on Spotify dataWould you like to add another really cool and interesting chart to your data visualization portfolio? Follow this simple tutorial and you’ll learn how to create a beautiful and interactive Angular Gauge using JavaScript, with ease!

An Angular Gauge, also known as a Circular Gauge, is a type of gauge chart with a radial scale. Such visualizations can nicely show a value within a range and are widely used in various dashboards.

The recent good news of vaccines feels like music to our ears. So, I thought why not take some interesting music data for visualization in this tutorial! The 63rd annual Grammy Awards ceremony will be held in March 2021, and when I looked through the list of the Record of the Year nominees, I wondered how popular each of these songs is. To find out, I decided to look at the number of their streams on Spotify, one of the world’s leading music streaming platforms, and thought that a Solid Angular Gauge could work well in such a visual analysis. It also resembles a vinyl record, which makes it an especially interesting chart type to opt for when representing such data!

So, along the tutorial, I will be visualizing Spotify stream counts for each 2021 GRAMMYs Record of the Year nominee song in a JS Angular Gauge chart. That is going to be entertaining! All aboard!
