Hello
# React-Muze

**React-Muze** is a React wrapper over the core [Muze](https://github.com/chartshq/muze) library. It provides React bindings for **Muze** and makes it easier to create charts using Muze for your React applications.

### What is Muze?
Muze is a free library for creating exploratory data visualizations in the browser that is powered by WebAssembly. It is ideal for use in visual analytics dashboards & applications to create highly performant, interactive, multi-dimensional, and composable visualizations with the Grammar of Graphics approach. More about Muze here: [https://muzejs.org/docs/wa/latest/introduction](https://muzejs.org/docs/wa/latest/introduction)

# Installation & Usage

## Installation

To use React-Muze in your React project, you need to install the **muze** and **react-muze** package from NPM.

```shell
npm install @chartshq/muze @chartshq/react-muze
```

Next, as Muze is built on top of WebAssembly, we need to copy some WebAssembly assets to our build directory. To accomplish that we are going to use the `copy-webpack-plugin` NPM package in our build config.

```shell
npm install [email protected] -D
```

### For a project created using Create-React-App

Since applications built with Create-React-App does not expose webpack config until ejected, we need to use the `react-app-rewired` package, to add the custom webpack config. How it works here: [react-app-rewired](https://github.com/timarney/react-app-rewired)

```shell
npm install react-app-rewired
```

Next, we need to create a file named `config-overrides.js` at the root of the project and add the following code in it

```javascript
const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require("path");
module.exports = function override(config, env) {
//add webpack copy plugin
const copyPlugin = new CopyWebpackPlugin([
{
from: path.resolve("node_modules", "@chartshq/muze/dist"),
to: '.',
}
]);
if (!config.plugins) {
config.plugins = [];
}
config.plugins.push(copyPlugin);
return config;
}
```

And finally, add the following scripts inside your `package.json` and you are ready to go

```json
{
"scripts": {
"start": "react-app-rewired start",
"build": "react-app-rewired build",
}
}
```

### For a custom React project

In a custom setup, since we have direct access to webpack config, we can simply add `copy-webpack-plugin` configuration directly inside out webpack config. Just add the following config in the `plugins` section of your `webpack.config.js` file

```javascript
{
plugins: [
new CopyWebpackPlugin([
{
from: path.resolve("node_modules", "@chartshq/muze/dist"),
to: '.',
}
])
]
}
```
## Creating your first Chart

For this illustration, we will be using the following data and schema.

```javascript
const data = [
{
Name: "chevrolet chevelle malibu",
Acceleration: 12,
},
{
Name: "buick skylark 320",
Acceleration: 11.5,
},
{
Name: "plymouth satellite",
Acceleration: 11,
},
{
Name: "amc rebel sst",
Acceleration: 12,
},
];
const schema = [
{
name: "Name",
type: "dimension",
},
{
name: "Acceleration",
type: "measure",
defAggFn: "avg",
},
];
```

### Step 1 - Import Muze, Canvas, DataModel as follows

```jsx
import Muze, { Canvas } from "@chartshq/react-muze/components";
```

### Step 2 - Create a DataModel Instance from the data

```jsx
async function createDataModel() {
const DataModelClass = await Muze.DataModel.onReady();
const formattedData = await DataModelClass.loadData(data, schema);
return new DataModelClass(formattedData);
}
```

### Step 3 - Rendering Muze

In the `render()` method of you react component, we need to put the following

```jsx
render() {
// carsDm is the a dataModel instance
// created from `data` and `schema`,
// and saved on state
const { carsDm } = this.state;

return (
<Muze data={carsDm}>
<Canvas rows={["Acceleration"]} columns={["Name"]} />
</Muze>
);
}
```

### Full Code of the example

```javascript
import React from "react";
import Muze, { Canvas } from "@chartshq/react-muze/components";

const data = [
{
Name: "chevrolet chevelle malibu",
Acceleration: 12,
},
{
Name: "buick skylark 320",
Acceleration: 11.5,
},
{
Name: "plymouth satellite",
Acceleration: 11,
},
{
Name: "amc rebel sst",
Acceleration: 12,
},
];
const schema = [
{
name: "Name",
type: "dimension",
},
{
name: "Acceleration",
type: "measure",
defAggFn: "avg",
},
];

async function createDataModel() {
const DataModelClass = await Muze.DataModel.onReady();
const formattedData = await DataModelClass.loadData(data, schema);
return new DataModelClass(formattedData);
}

class Chart extends React.Component {
constructor(props) {
super(props);
this.state = {
carsDm: null,
};
}

componentDidMount() {
createDataModel().then((carsDm) => {
this.setState({ carsDm });
});
}

render() {
const { carsDm } = this.state;

return (
<Muze data={carsDm}>
<Canvas rows={["Acceleration"]} columns={["Name"]} />
</Muze>
);
}
}

export default Chart;
```

# Examples

In the example directory, you will find a react application that has many examples as individual components.

### How to run the examples

Setup the project in your local environment

```shell
yarn install
yarn build
cd dist && yarn link / npm link --only=production
yarn watch-build
```

Go to the examples directory and run the following commands

```shell
yarn install
yarn link @chartshq/react-muze
yarn start
```

To try out all the other examples, inside the `examples/src/index.js` file import an example component and render on `jsx`. For example,

```jsx
// import BoxPlot from './Examples/Composability/BoxPlot';
import SimplePieChart from './Examples/Pie/SimplePie';

ReactDOM.render(
<React.StrictMode>
<SimplePieChart />
</React.StrictMode>,
document.getElementById("root")
);
```
