Charting a Course with React-Muze: Unleashing Data Visualization Magic

React-Muze is a powerful React wrapper for the Muze library, bringing the magic of WebAssembly-powered data visualization to your React applications. This library allows developers to create highly interactive, multi-dimensional, and composable visualizations using the Grammar of Graphics approach. Whether you’re building complex dashboards or simple charts, React-Muze provides the tools to bring your data to life.

Features

React-Muze inherits the robust features of the core Muze library while providing a React-friendly interface:

• WebAssembly-powered performance for smooth and responsive visualizations
• Grammar of Graphics approach for flexible and composable chart creation
• Support for multi-dimensional data visualization
• Highly interactive charts with built-in exploration capabilities
• Seamless integration with React components and lifecycle

Installation

To get started with React-Muze, you’ll need to install both the core Muze library and the React wrapper. Open your terminal and run the following command:

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

Since Muze relies on WebAssembly, you’ll also need to set up your build process to handle the necessary assets. For projects using webpack, install the copy-webpack-plugin:

npm install copy-webpack-plugin@5.1.1 -D

Setting Up Your Build

For Create-React-App Projects

If you’re using Create-React-App, you’ll need to customize the webpack configuration without ejecting. Install react-app-rewired:

npm install react-app-rewired

Create a config-overrides.js file in your project root with the following content:

const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require("path");

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

Update your package.json scripts:

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

For Custom React Projects

If you have a custom webpack setup, add the following to your webpack.config.js:

const CopyWebpackPlugin = require('copy-webpack-plugin');
const path = require("path");

module.exports = {
  // ... other config
  plugins: [
    new CopyWebpackPlugin([
      { from: path.resolve("node_modules", "@chartshq/muze/dist"), to: '.' }
    ])
  ]
};

Creating Your First Chart

Let’s create a simple bar chart to demonstrate the power of React-Muze.

Preparing the Data

First, we’ll define our data and schema:

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" }
];

Creating a DataModel

React-Muze requires a DataModel instance. Here’s how to create one:

import Muze from "@chartshq/react-muze/components";

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

Rendering the Chart

Now, let’s create a React component to render our chart:

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

const Chart: React.FC = () => {
  const [carsDm, setCarsDm] = useState(null);

  useEffect(() => {
    createDataModel().then(setCarsDm);
  }, []);

  if (!carsDm) return <div>Loading...</div>;

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

export default Chart;

This code creates a simple bar chart showing the acceleration of different car models.

Advanced Usage

React-Muze offers a wide range of customization options for creating complex visualizations.

Adding Interactivity

Let’s enhance our chart with some interactive features:

<Muze data={carsDm}>
  <Canvas
    rows={["Acceleration"]}
    columns={["Name"]}
    config={{
      interaction: {
        tooltip: { enabled: true },
        zoom: { enabled: true },
        pan: { enabled: true }
      }
    }}
  />
</Muze>

This configuration enables tooltips, zooming, and panning on our chart.

Multi-dimensional Visualization

React-Muze excels at handling multi-dimensional data. Let’s create a scatter plot with additional dimensions:

const data = [
  { Name: "chevrolet chevelle malibu", Acceleration: 12, Horsepower: 130, Weight: 3504 },
  { Name: "buick skylark 320", Acceleration: 11.5, Horsepower: 165, Weight: 3693 },
  { Name: "plymouth satellite", Acceleration: 11, Horsepower: 150, Weight: 3436 },
  { Name: "amc rebel sst", Acceleration: 12, Horsepower: 150, Weight: 3433 }
];

const schema = [
  { name: "Name", type: "dimension" },
  { name: "Acceleration", type: "measure" },
  { name: "Horsepower", type: "measure" },
  { name: "Weight", type: "measure" }
];

// In your component:
<Muze data={carsDm}>
  <Canvas
    rows={["Acceleration"]}
    columns={["Horsepower"]}
    color={["Name"]}
    size={["Weight"]}
    config={{
      mark: { shape: "point" }
    }}
  />
</Muze>

This creates a scatter plot where each point represents a car, with its position determined by acceleration and horsepower, color representing the car name, and size representing the weight.

Conclusion
