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 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!

July 13th, 2021 by Shachee Swadia

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.

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.
