The Working Approach
chart-animation builds moving charts whose numbers and geometry come from the current video frame. It separates the scale that maps data to pixels from the interpolation that maps frames to changing values. That distinction matters when a chart library's own timer would disagree with an offline renderer.
The documented workflow uses Remotion for rendered output and keeps datasets in input props. It covers growing bars, counters, line reveals and ranking sequences. Exact labels, units and final values are checked in rendered stills before encoding a video or repeating the design across several datasets.
Expected Deliverables
- A frame-driven Remotion chart composition.
- An MP4 and reusable dataset/theme inputs.
- Representative stills for checking labels, ranks and values.
From Brief to Review
- 01Validate the dataset mapping
Identify the time field, series, units and value range. Register the Remotion composition with its input schema and default props, while keeping the dataset separate from the theme. When row count determines video length, derive duration through calculateMetadata so a different dataset does not retain the previous video's length.
- 02Drive changes from frames
Calculate values and positions using the frame clock. Disable competing chart-library animation loops and format the displayed values after rounding.
- 03Inspect before encoding
Render beginning, intermediate and final stills with the actual delivery props. Check exact numbers, rank changes, labels and scale before rendering the full MP4.
