JavaScript Drawing Library GraphicsJS 1.2.0 Released + Introduction from SitePoint
May 3rd, 2017 by AnyChart TeamGraphicsJS, our powerful JavaScript drawing library that we open-sourced last year, has recently got an update to version 1.2.0. It is the next best news of 2017, a great addition to winning a Devies Award with GraphicsJS for the category “JavaScript Technologies” and to the 7.13.0/7.13.1 releases of our JS/HTML5 charting solutions AnyChart, AnyStock, AnyMap, and AnyGantt.
So, we invite you to take a very quick look at the most important updates (we’ll highlight the two below). And then – in case you want to feel the real power of JavaScript drawing and have not used GraphicsJS in your business or fun web projects yet – we are sharing a nice article published on SitePoint just recently. It is an introduction to GraphicsJS based on two tutorials. They will guide you through the most valuable features of this JavaScript drawing library and demonstrate them in action, and you’ll learn how to easily create a naïve art picture and a time-killer game.
JavaScript Drawing with GraphicsJS: Main Improvements
- Closure library and Closure compiler were updated to version 20161024.
- Enjoy an improved JavaScript drawing performance! In particular, we optimized the process of obtaining a link to a container for the stage. Also, resize events are now handled with the help of the Timer object, not the iFrame element.
Now, you are welcome to read the SitePoint article about GraphicsJS. Please do not forget to ask your questions, if any. You may do that by leaving a comment here right below the article.

We are back with another collection of interesting charts, maps and infographics being popular lately. As you probably noticed, our Data Visualization Weekly series took a short break. In fact, no new issue came out last week. But the reason is simple and (hopefully) excusable. In fact, we were working really hard to get things done with the exciting major 7.13.0 update that our JavaScript charting libraries has received earlier this week.
Now the source code of AnyChart, AnyMap, AnyStock and AnyGantt is open. Plugins for all popular JS frameworks are available. And all the new features from the 7.13.0 release work great. That means we can finally get back to you to showcase new data visualizations that people followed most on our Twitter, Facebook and LinkedIn accounts over the last days. Moreover, the current issue of Data Visualization Weekly will cover the last two weeks instead of just one, to reimburse you for the delay. So, let’s take a look at the following great visual pieces now:
- Most Popular Girl Scout Cookies;
- History of Global Living Conditions in Interesting Charts;
- Interactive Map of Popular Surfing Areas in France;
- Most Popular Brands in Each Country;
- PERT Chart of Airplane Design Process;
- Revealing Age of Buildings in New York City.
