Worked Example: Adding a Block

Scenario

User has an existing HyperFrames project and wants to add an animated chart alongside their video content.

Steps

1. Install the block

hyperframes add data-chart

2. Wire into index.html

<div id="stage" data-composition-id="main" data-width="1920" data-height="1080" data-duration="30">
  <video
    id="speaker"
    src="speaker.mp4"
    data-start="0"
    data-duration="30"
    data-track-index="0"
    style="position: absolute; width: 60%; height: 100%; left: 0; top: 0; object-fit: cover;"
  ></video>

  <!-- Data chart appears at 5s in the right 40% of the screen -->
  <div
    data-composition-id="data-chart"
    data-composition-src="compositions/data-chart.html"
    data-start="5"
    data-duration="15"
    data-track-index="1"
    data-width="1920"
    data-height="1080"
    style="position: absolute; right: 0; top: 0; width: 40%; height: 100%;"
  ></div>
</div>

3. Lint and preview

hyperframes lint
hyperframes preview

4. Customize (optional)

Edit compositions/data-chart.html — data arrays are at the top of the script, colors are in the CSS rules scoped under [data-composition-id="data-chart"].
