Top 25 Programming Languages Visualized
Since I began working with SLIM-Metrics and the QSM historical database, I've been interested in unique ways to present information. I've written before about how others pair data and design to visualize patterns, but this is my first attempt: a word cloud.
A word cloud is a graphical representation of how often a word is used within a sample. The larger the font in the word cloud, the more often it is used in the sample. Word clouds are a great tool for displaying sensitive data without having to use numbers. The above word cloud visualizes the entire QSM database, going back three decades.
What I like about this visualization is that at a glance, you can tell that more projects use PL/1 than Natural, simply by examining font size. Even without knowing exactly how many Java projects are in the QSM database, you can still determine that it's more than Visual Basic, but less than COBOL.
Unsurprisingly, COBOL still has a large market share in the QSM database. Most COBOL projects completed after 2000 were maintenance projects, not new development.
