3 things to look at
- 14 days oldThe repository was created 14 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Remotion Data Viz
Animated data visualizations as Remotion compositions — frame-deterministic, React-based, seekable.
For the composition contract see remotion-core. For animation primitives see remotion-animation.
Core principle
Data visualizations in Remotion are animated from frame 0 to durationInFrames. All chart values are derived from useCurrentFrame() — there is no re-render on resize or data change, only a deterministic mapping of frame → visual state.
Common patterns
Animated counter
import {useCurrentFrame, useVideoConfig, interpolate} from 'remotion';
type CounterProps = {
from: number;
to: number;
durationInFrames: number;
prefix?: string;
suffix?: string;
};
const AnimatedCounter: React.FC<CounterProps> = ({from, to, durationInFrames, prefix = '', suffix = ''}) => {
const frame = useCurrentFrame();
const value = interpolate(frame, [0, durationInFrames], [from, to], {
extrapolateRight: 'clamp',
easing: (t) => t < 0.5 ? 2 * t * t : -1 + (4 - 2 * t) * t, // ease-in-out-quad
});
return (
<div style={{fontSize: 120, fontWeight: 700, color: '#fff', fontVariantNumeric: 'tabular-nums'}}>
{prefix}{Math.round(value).toLocaleString()}{suffix}
</div>
);
};
Bar chart reveal
import {interpolate, useCurrentFrame} from 'remotion';
type BarProps = {label: string; value: number; maxValue: number; index: number; color: string};
const AnimatedBar: React.FC<BarProps> = ({label, value, maxValue, index, color}) => {
const frame = useCurrentFrame();
const STAGGER = 5;
const DURATION = 40;
const progress = interpolate(
frame,
[index * STAGGER, index * STAGGER + DURATION],
[0, 1],
{extrapolateLeft: 'clamp', extrapolateRight: 'clamp'}
);
const barWidth = (value / maxValue) * 600 * progress;
return (
<div style={{marginBottom: 20}}>
<div style={{color: '#ccc', fontSize: 24, marginBottom: 8}}>{label}</div>
<div style={{height: 48, backgroundColor: '#1e1e2e', borderRadius: 8, overflow: 'hidden'}}>
<div
style={{
height: '100%',
width: barWidth,
backgroundColor: color,
borderRadius: 8,
display: 'flex',
alignItems: 'center',
paddingLeft: 16,
}}
>
<span style={{color: 'white', fontWeight: 700}}>{Math.round(value * progress).toLocaleString()}</span>
</div>
</div>
</div>
);
};
Line chart draw (SVG)
import {interpolate, useCurrentFrame} from 'remotion';
const LineChart: React.FC<{data: number[]; width: number; height: number}> = ({data, width, height}) => {
const frame = useCurrentFrame();
const {durationInFrames} = useVideoConfig();
const progress = interpolate(frame, [0, durationInFrames * 0.8], [0, 1], {extrapolateRight: 'clamp'});
const maxVal = Math.max(...data);
const points = data
.slice(0, Math.ceil(data.length * progress))
.map((v, i) => `${(i / (data.length - 1)) * width},${height - (v / maxVal) * height}`)
.join(' ');
return (
<svg width={width} height={height}>
<polyline
points={points}
fill="none"
stroke="#6366f1"
strokeWidth={4}
strokeLinecap="round"
strokeLinejoin="round"
/>
</svg>
);
};
Pie / donut reveal
const DonutChart: React.FC<{segments: {value: number; color: string}[]; size: number}> = ({segments, size}) => {
const frame = useCurrentFrame();
const {durationInFrames} = useVideoConfig();
const progress = interpolate(frame, [0, durationInFrames * 0.7], [0, 1], {extrapolateRight: 'clamp'});
const radius = size / 2 - 20;
const cx = size / 2;
const cy = size / 2;
const total = segments.reduce((s, seg) => s + seg.value, 0);
let cumulative = 0;
const paths = segments.map((seg, i) => {
const startAngle = (cumulative / total) * 2 * Math.PI - Math.PI / 2;
cumulative += seg.value;
const endAngle = (cumulative / total) * 2 * Math.PI * progress - Math.PI / 2;
const x1 = cx + radius * Math.cos(startAngle);
const y1 = cy + radius * Math.sin(startAngle);
const x2 = cx + radius * Math.cos(endAngle);
const y2 = cy + radius * Math.sin(endAngle);
const largeArc = endAngle - startAngle > Math.PI ? 1 : 0;
return (
<path
key={i}
d={`M ${cx} ${cy} L ${x1} ${y1} A ${radius} ${radius} 0 ${largeArc} 1 ${x2} ${y2} Z`}
fill={seg.color}
/>
);
});
return <svg width={size} height={size}>{paths}</svg>;
};
Using recharts
npm install recharts
Important: recharts uses
requestAnimationFrameand DOM measurements internally. Usespring()andinterpolate()to compute chart data values before passing to recharts — do not rely on recharts' internal animation (it's not frame-deterministic).
import {BarChart, Bar, XAxis, YAxis} from 'recharts';
const MyChart: React.FC = () => {
const frame = useCurrentFrame();
const progress = interpolate(frame, [0, 60], [0, 1], {extrapolateRight: 'clamp'});
const data = [
{name: 'A', value: Math.round(1200 * progress)},
{name: 'B', value: Math.round(800 * progress)},
{name: 'C', value: Math.round(1600 * progress)},
];
return (
<BarChart width={600} height={400} data={data}>
<XAxis dataKey="name" />
<YAxis />
<Bar dataKey="value" fill="#6366f1" isAnimationActive={false} />
</BarChart>
);
};
Always set isAnimationActive={false} on recharts components — their internal animation is not frame-deterministic.
calculateMetadata for data-driven compositions
When the composition duration depends on the data length, use calculateMetadata:
import {Composition} from 'remotion';
type DataVizProps = {data: {label: string; value: number}[]};
const dataViz = {
component: DataVizScene,
calculateMetadata: async ({props}: {props: DataVizProps}) => {
const fps = 30;
const framesPerBar = 20;
const durationInFrames = props.data.length * framesPerBar + 60; // padding
return {durationInFrames, fps};
},
};
