 # Visualization Framework
 
-## Installation
+This repository contains two packages.
 
-You can use yarn to install the core library:
+## @hediet/visualization-core
 
-```
-yarn add @hediet/visualization-core
-```
+This package provides basic infrastructure for implementing visualizations.
+See its readme [here](./visualization-core/README.md).
 
-If you want to use the existing visualizations, add the bundle library:
+## @hediet/visualization-bundle
 
-```
-yarn add @hediet/visualization-bundle
-```
+This package bundles all the visualizations.
+See its readme [here](./visualization-bundle/README.md).
 
-## Usage
-
-Import `@hediet/visualization-bundle` to register all default visualizations:
-
-```tsx
-// This registers all visualizations
-import "@hediet/visualization-bundle";
-```
-
-Don't forget to import the styles in your scss file:
-
-```scss
-@import "~@hediet/visualization-bundle/style.scss";
-```
-
-Use `globalVisualizationFactory` to visualize some data:
-
-```tsx
-import { globalVisualizationFactory } from "@hediet/visualization-core";
-
-const data = {
-	kind: { graph: true as true },
-	nodes: [
-		{ id: "1", label: "1" },
-		{ id: "2", label: "2", color: "orange" },
-		{ id: "3", label: "3" },
-	],
-	edges: [
-		{ from: "1", to: "2", color: "red" },
-		{ from: "1", to: "3" },
-	],
-};
-
-const visualizations = globalVisualizationFactory.getVisualizations(
-	data,
-	/* preferred visualization id */ undefined
-);
-// `visualizations.bestVisualization` is the visualization that is best suited to visualize the data.
-// `visualiztaions.allVisualizations` contains all suitable visualizations.
-```
-
-If you use react, you can use the `VisualizationView` component to render a visualization:
-
-```tsx
-import { VisualizationView, Theme } from "@hediet/visualization-core";
-
-// const visualizations = ...
-
-function App() {
-	if (!visualizations.bestVisualization) {
-		return null;
-	}
-	return (
-		<VisualizationView
-			theme={Theme.light}
-			visualization={visualizations.bestVisualization}
-		/>
-	);
-}
-```
+If you want to add your own visualization to this project, visualization-bundle is the right place!
+The readme documents how to implement your own visualization.
