AECharts is a web-based tool for creating animated chart videos. Users paste or upload data, choose a template, customize the styling, and export a polished MP4 โ€” no video editing software or design skills required.
The workflow is simple: bring in your data via paste, CSV, Excel, or Google Sheets. AECharts parses it automatically. Select a chart type and template, customize colors, fonts, labels, and animation speed in a live-preview editor. When you're done, export a full MP4 video ready for presentations, social media, or reports.

Chart types include: - Vertical and horizontal bar charts for category comparisons - Line charts for time-series trends - Pie charts for part-to-whole relationships - Bar race charts for animated rankings over time - Gauge, waffle, and Sankey diagrams for specialized use cases

The rendering engine is built on PixiJS (WebGL) and GSAP animations, producing smooth, high-quality output. Templates are designed to follow data visualization best practices out of the box.

User accounts are backed by Firebase with automatic cloud saving โ€” no save button, no lost work. Your file library persists across sessions with full edit history.

AECharts is built for marketers, founders, journalists, and content creators who want to turn data into compelling visual stories without the overhead of motion graphics tools. Where Datawrapper and Flourish made static charts accessible to non-designers, AECharts does the same for animated video.

  • Limited by Python Version
    The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
  • Performance Overhead
    The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
  • Less Community Support
    Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
  • Dependency Management
    Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
