  • Dynamic infographic and banner generation system

    Infographics
    Development of a software complex for the automatic creation of visual content based on dynamic data. The solution allows for the generation of branded reports, banners, and educational materials without the involvement of a designer.

    Functional capabilities:
    — Automatic rendering of graphs, charts, and text blocks using the Pillow (PIL) and Matplotlib libraries.
    … — Working with templates: dynamic data substitution, changing color schemes and fonts in real time.
    — Processing large data sets and exporting to high-resolution formats (JPG, PNG, PDF).
    — Implementation of layout algorithms for correct display of content of any length.

    Result:
    Reduction of time for creating operational reports and advertising creatives by 90%. The system is ideal for EdTech projects, fintech dashboards, and SMM automation.
