01 What It Does

Render data charts with exact values and frame-driven movement

Build chart videos with frame-driven values, readable counters, ranking transitions and dataset checks before Remotion export.

Source-based workflowNot an execution benchmark

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.
See the Example Brief

From Brief to Review

  1. 01
    Validate 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.

  2. 02
    Drive changes from frames

    Calculate values and positions using the frame clock. Disable competing chart-library animation loops and format the displayed values after rounding.

  3. 03
    Inspect 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.

02 When to Use It

When to Use It

The source workflow depends on Remotion and any selected chart or scale packages.

A Good Fit

  • Data must stay exact in videoUse it for a chart where a wrong digit or incorrect column mapping would change the message.
  • One chart design has many datasetsValidated props and shared theme settings support repeated renders from the same source project.

Limits to Check

  • It needs a rendering environmentThe source workflow depends on Remotion and any selected chart or scale packages.
  • Animation does not validate the storyThe dataset and interpretation must be supplied and checked; smooth bars do not establish that a metric is meaningful.

Bring These Inputs

  • Structured recordsSupply CSV or JSON with clear series identities and time fields.
  • Metric definitionsSpecify units, rounding, labels and any event that deserves a pause.
  • Video targetState duration, aspect, frame rate and the intended viewing size.

03 Decisions That Matter

Decisions That Matter

  1. Deterministic values

    Seeking the same frame yields the same displayed data instead of a timer-dependent state.

  2. Readable counters

    Formatting and tabular digits keep changing numbers stable on screen.

  3. Representative batch checks

    A real dataset can expose a mapping or layout defect before it is copied into many files.

Review the Source and Setup

Supply CSV or JSON with clear series identities and time fields.

Start With One Deliverable

Adapt the scope, source material and constraints in this brief before running the skill.

Example Brief
Use chart-animation to make a 15-second ranking video from my monthly sales CSV. Keep the five product names and revenue values exactly as supplied, with currency units visible. Show a short initial hold, animate the ranking changes, pause at the first leadership crossover and hold the final result long enough to read. Drive values and positions from the video frame, with stable series identities and tabular digits. Render representative stills using the actual CSV-derived props before encoding. Deliver the MP4, reusable composition and a note identifying the data columns used.

Inspect the Result

Check the actual output against these observable criteria.

  • Match rendered labels, units and final values to the supplied records.
  • Check interpolated ranking movement and off-canvas labels.
  • Confirm the actual input props, final duration and decoded video.

06 Questions Before You Start

Questions Before You Start

Can I use D3?

The source uses D3 for scales and shapes while keeping time under the video renderer. D3 transitions or other independent animation clocks should not drive exported frames.

Why inspect stills before the video?

A still makes wrong values, swapped columns and clipped labels easier to identify. The source requires checks using the actual delivered dataset.

Can it render multiple CSV files?

The documented pattern passes each dataset as props to one composition. Validate a representative dataset before expanding to the batch.
