Building a Word Tree Chart with JavaScript

October 4th, 2021 by Shachee Swadia

Word Tree Chart built with JavaScript HTML5 on a screenData visualization is not only useful for communicating insights but also helpful for data exploration. There are a whole lot of different chart types that are widely used for identifying patterns in data. One of the lesser-used chart types is Word Tree. It is a very interesting visualization form, quite effective in analyzing texts. And right now, I will teach you how to quickly create nice interactive word tree charts using JavaScript.

Word trees display how a set of selected words are connected to other words in text data with a branching layout. These charts are similar to word clouds where words that occur more frequently are shown bigger. But they are different in the sense that word trees also show the connection between the words, which adds context and helps find patterns.

In this tutorial, I will create a lovely word tree from the text of the very famous book The Little Prince by French aviator and writer Antoine de Saint-Exupéry. Check out a demonstration of the final chart below and keep reading to learn how this and any other interactive JS word tree can be built with ease.

AnyChart Used for Data Visualization in Open-Source Redis Inventory Tool

September 29th, 2021 by AnyChart Team

A sunburst diagram in open-source Redis Inventory tool, visualizing Redis memory usage hierarchically, built with the AnyChart JavaScript charting librarySunburst charts are known to be greatly useful for visualizing hierarchical data structures. So it is no surprise that this chart type became a big hit among our users immediately after we added it to the AnyChart JavaScript library. Because the core of our global customer base is enterprise clients, most of the real-world use cases for our JS sunburst chart are hidden in internal corporate apps. But AnyChart is often picked for data visualization in open projects as well, and we invite you to see a super cool example we have recently found out about — Redis Inventory. It is an open-source tool that makes it easy to view Redis memory usage by key patterns in a hierarchical way, with an interactive sunburst chart in action.

Learn more about Redis Inventory and how AnyChart is used there from our quick interview with its creator Aleksandr Obukhov. (Stack: Go/Cobra/Redis.)

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!

Yarra Hills Secondary College Uses AnyChart to Visualize Student Progress on Digital Data Wall

August 10th, 2021 by AnyChart Team

Official logo of Yarra Hills Secondary College using AnyChart to visualize student progress on Digital Data WallLeading the enterprise data visualization market, AnyChart is also widely used by not-for-profit organizations in sectors such as education. Stephen Blackwell from Yarra Hills Secondary College (Australia) has recently shown us another great example of such an application.

Data walls have become a widespread practice in schools across the globe, letting teachers track and benchmark student progress to create effective learning environment. In many cases, they are just physical. For Yarra Hills, Stephen created a digital one that supercharges the overview with the help of well-thought-out visualizations powered by our JavaScript charting library.

Stephen kindly agreed to tell us about his Digital Data Wall project and how AnyChart is implemented. Read our fresh interview below. As you can imagine the original web app is for internal use only, but if you want to take a glance here is a copy with de-identified student data (password anychArt) and this is an example of an individual student profile.

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 Flow Map Built using JavaScript in Four StepsA step-by-step tutorial showing how to create an interactive JS Flow Map. Illustrated by visualizing data on migration to the US.

It may seem to be complicated to create an interactive Flow Map for the Web using JavaScript. But it’s not! This easy-to-follow tutorial will show you how to build beautiful JS flow maps without too much effort.

In these difficult times of the pandemic, there is a lot of confusion and concern about the immigration status of people around the globe. I decided to take a look at the immigration data of the US which has more migrants than any other country in the world. Here, I explore where these immigrants come from and represent the top 15 countries that contributed the highest number of migrants to the US in the year 2019.

A flow map seems the perfect way to showcase the inflow of migrants into the United States from various countries. Before going further, let me give you a brief idea about a flow map and its uses.
