AnyChart Used to Power Charts in Data Science Teaching Project Made at Edinburgh Napier University

September 16th, 2021 by AnyChart Team

JavaScript charts powered by AnyChart in a data science teaching website project created at Edinburgh Napier UniversityAt AnyChart, we are eager to support education projects by letting their creators work gratis with the same data visualization solutions used by the world’s leading companies to build interactive charts.

Recently, a group of students at Edinburgh Napier University — including Martin McVey, Tibor Toth, Daniel Glen, Flynn Kearney, David Stewart, and John Frampton — reached out to us as they were building a website to assist with the learning of data science. And we were more than happy to provide them with a free license for the use of our JavaScript charting library.

The website is now available to the public, presenting a wide range of chart types with real-world examples along with questions and answers. Acknowledged as one of the top projects in the university year and awarded with a prize from Computershare, it is to be used for teaching about data visualization and analytics in Scottish schools.

We thought you could be interested to not only check out the website but also learn some more about the project and its developers’ experience with AnyChart. So we had a quick talk on that with Martin McVey from the team. Read below.

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!
