Survey results data visualization

DOU—Developers of Ukraine—is the largest Tech Community in Ukraine. An important part of dou.ua media is the analytical section with a large number of regular publications: monthly job market review, semiannual salary report and tech companies rating, annual employers rating, industry gender state research, tech specialist portrait, skill maps, et al.

I visualized the data for these analytics by developing interactive modules to embed in online publications. I kept visualizations simple with basic interactivity: multi-category data filtering, tooltips for details, case-specific animations and annotations.

In addition to actual charts, I prepared marketing covers and banners to promote publications.
