# Packed bubbles

> Items as bubbles, sized by volume. Sample data: spot volume by asset, ETH +5.8%, SOL −3.4%.

- Type 035 · Part of a whole
- Component: `<PackedBubbles>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/packed-bubbles` (free in Hearth: the public registry, no token; Signal with Code and Complete)
- Type page: https://usechartory.com/charts/packed-bubbles

## Installation

1. **Set up the registry once.** This chart is free in Hearth and MIT licensed: no token. Add @chartory to components.json once (the URL alone, no headers), or skip this when another chart is already installed. [Installation guide](https://usechartory.com/docs/installation)

2. **Add the chart.** One command adds the Packed bubbles component to your project.

```bash
npx shadcn add @chartory/packed-bubbles
```

3. **Use it.** Pass your rows. The props are the Figma properties.

usage.tsx:

```tsx
import { PackedBubbles }
  from "@/components/chartory/packed-bubbles"

<PackedBubbles
  data={assetVolume}
  size="m"
  legend
/>
```

### `<PackedBubbles>`

Every prop but data is a Figma property with the same name and values.

## Packed bubble chart: a React and Figma chart in four sizes

### What does a packed bubble chart show?

A packed bubble chart draws each item as a circle sized by its value and packs them together, with colour for a second signal such as up or down. Use it for trading volume, mentions or spend when size and one status matter.

Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.

### What is the Packed bubbles component?

It is one **<PackedBubbles>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is a size value and a % change per item.

Sizes **XS**, **S**, **M** and **L** re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.

### When should I use it?

- **Is a rough size enough?** Yes means the packed bubbles fit.
- **Is there a second signal?** Yes means the packed bubbles fit.
- **Are the items independent?** Yes means the packed bubbles fit.

### When does another type fit better?

- **Exact values matter.** Use Horizontal bars instead.
- **Size only, in groups.** Use Treemap instead.
- **Items with links between them.** Use Network instead.

## Packed bubble questions

### Does the Packed bubbles chart work with shadcn/ui?

Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.

### How do I install it?

It is free in Hearth and MIT licensed: add the @chartory registry URL once, no token, then run npx shadcn add @chartory/packed-bubbles. The Installation guide has the steps.

### Can my coding agent install it?

Yes. Connect the Chartory MCP server and ask for the packed bubbles chart; the agent runs the same command and you review the diff.

### What data does it expect?

A size value and a % change per item. The sample data comes with the component, and the props table lists every field.

### Which sizes does it ship in?

XS, S, M and L, in Figma and in code. Each size is laid out again from the data, so text and lines keep their size.

### Is it in the Figma file too?

Yes. chart/035-packed-bubbles has the same properties as the component.

### Does it follow light and dark mode?

Yes. Every paint is a token, so the chart follows light and dark mode and the collection you pick.

### Which plan has the code?

None for Hearth: it is free in the public registry, no token. The Signal collection (@chartory/signal) comes with Code and Complete.
