Playfair 1.0.0 Release
In the meantime, a lot has happened and the release of Playfair 1.0.0 was forgotten. We would like to make up for this omission and briefly present the highlights of the release.

Spider Charts with Playfair
Spider charts, also known as radar charts, are among the most versatile tools for data visualization. These circular charts make it possible to display multiple variables simultaneously and present complex data sets in an intuitive form. They are particularly valuable for analyzing performance indicators, evaluations, or comparisons between different objects or time periods. Wouldn’t it be nice to have Playfair generate spider charts?
Playfair with EchoSVG
You may have noticed that the Playfair project started with the JFreeSVG library and has now switched to the EchoSVG library. Both libraries have their advantages and disadvantages, but JFreeSVG’s GPL 3.0 license in particular makes working with it difficult in many projects, often even impossible. With the next version 0.7.0, Playfair will switch to the Apache 2.0 license. This would be a little too little content for a blog post, so let’s take a look at one of EchoSVG’s weaknesses.
Diagram As Code
I recently sat in a lecture about PlantUML and the advantages of Diagram As Code. Diagram As Code is a special variant of Documentation As Code. It is the possibility for software developers to create their documentation in the form of text files without the use of word processing systems. The advantage is obvious, the developer can use his documentation like his source code. Versioning, automatically creating comparisons, transforming, validating and much more. This gave me the idea of developing something similar.
