This section explains you the steps required to create a TreeMap control and demonstrate its basic usage.

Dependencies

The following list of minimum dependencies are required to use the TreeMap control:

|-- @syncfusion/ej2-react-treemap
    |-- @syncfusion/ej2-treemap
    |-- @syncfusion/ej2-base
    |-- @syncfusion/ej2-data
    |-- @syncfusion/ej2-pdf-export
    |-- @syncfusion/ej2-svg-base
|-- @syncfusion/ej2-react-base

Installation and configuration

To easily set up a React application, use create-vite-app, which provides a faster development environment, smaller bundle sizes, and optimized builds compared to traditional tools like create-react-app. For detailed steps, refer to the Vite installation instructions. Vite sets up your environment using JavaScript and optimizes your application for production.

Note: To create a React application using create-react-app, refer to this documentation for more details.

To create a new React application, run the following command.

npm create vite@latest my-app

To set-up a React application in TypeScript environment, run the following command.

npm create vite@latest my-app -- --template react-ts
cd my-app
npm run dev

To set-up a React application in JavaScript environment, run the following command.

npm create vite@latest my-app -- --template react
cd my-app
npm run dev

Adding Syncfusion^® packages

All the available Essential^® JS 2 packages are published in npmjs.com public registry. To install TreeMap package, use the following command.

npm install @syncfusion/ej2-react-treemap --save

Add TreeMap to project

Now, the TreeMap component can be added in the application. To initialize the TreeMap control in the React application, import the TreeMap control in the src/App.js
or src/App.tsx as per the application. Please use the below code to include the TreeMap component in the application.

import * as React from 'react';
import * as ReactDOM from "react-dom";
import { TreeMapComponent } from '@syncfusion/ej2-react-treemap';

export function App() {
  return ( <TreeMapComponent 
        height= '350px'
        dataSource={[
            { Title: 'State wise International Airport count in South America', State: "Brazil", Count: 25 },
            { Title: 'State wise International Airport count in South America', State: "Colombia", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Argentina", Count: 9 },
            { Title: 'State wise International Airport count in South America', State: "Ecuador", Count: 7 },
            { Title: 'State wise International Airport count in South America', State: "Chile", Count: 6 },
            ]}
            weightValuePath='Count'
            leafItemSettings= { {
                labelPath: 'State'
            }}>
        </TreeMapComponent> );
}

export default App;

Run the application

Now run the npm run dev command in the console to start the development server. This command compiles your code and serves the application locally, opening it in the browser.

npm run dev

Module injection

The TreeMap control is segregated into individual feature-wise modules. To use a particular feature, inject its feature module using the <Inject services={} /> method. You can find the modules available in TreeMap and their descriptions below.

TreeMapHighlight - Inject this provider to use highlight feature.
TreeMapSelection - Inject this provider to use selection feature.
TreeMapLegend - Inject this provider to use legend feature.
TreeMapTooltip - Inject this provider to use tooltip series.

Render TreeMap

This section explains how to render the TreeMap with data source. In the below example, TreeMap is modified to visualize international airport count in South America.

index.jsx
index.tsx
import * as React from "react";
import * as ReactDOM from "react-dom";
import { TreeMapComponent, Inject } from '@syncfusion/ej2-react-treemap';

export function App() {
  return ( <TreeMapComponent 
        height= '350px'
        dataSource={[
            { Title: 'State wise International Airport count in South America', State: "Brazil", Count: 25 },
            { Title: 'State wise International Airport count in South America', State: "Colombia", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Argentina", Count: 9 },
            { Title: 'State wise International Airport count in South America', State: "Ecuador", Count: 7 },
            { Title: 'State wise International Airport count in South America', State: "Chile", Count: 6 },
            { Title: 'State wise International Airport count in South America', State: "Peru", Count: 3 },
            { Title: 'State wise International Airport count in South America', State: "Venezuela", Count: 3 },
            { Title: 'State wise International Airport count in South America', State: "Bolivia", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Paraguay", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Uruguay", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Falkland Islands", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "French Guiana", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Guyana", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Suriname", Count: 1 },
            ]}
            weightValuePath='Count'
            leafItemSettings= { {
                labelPath: 'State'
            }}>
        </TreeMapComponent> );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);
import * as React from "react";
import * as ReactDOM from "react-dom";
import { TreeMapComponent, Inject } from '@syncfusion/ej2-react-treemap';

export function App() {
  return ( <TreeMapComponent 
        height= '350px'
        dataSource={[
            { Title: 'State wise International Airport count in South America', State: "Brazil", Count: 25 },
            { Title: 'State wise International Airport count in South America', State: "Colombia", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Argentina", Count: 9 },
            { Title: 'State wise International Airport count in South America', State: "Ecuador", Count: 7 },
            { Title: 'State wise International Airport count in South America', State: "Chile", Count: 6 },
            { Title: 'State wise International Airport count in South America', State: "Peru", Count: 3 },
            { Title: 'State wise International Airport count in South America', State: "Venezuela", Count: 3 },
            { Title: 'State wise International Airport count in South America', State: "Bolivia", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Paraguay", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Uruguay", Count: 2 },
            { Title: 'State wise International Airport count in South America', State: "Falkland Islands", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "French Guiana", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Guyana", Count: 1 },
            { Title: 'State wise International Airport count in South America', State: "Suriname", Count: 1 },
            ]}
            weightValuePath='Count'
            leafItemSettings= { {
                labelPath: 'State'
            }}>
        </TreeMapComponent> );
}

const root = ReactDOM.createRoot(document.getElementById('container'));
root.render(<App />);

Here, the TreeMap is created with data source and the weightValuePath property is set to the data source’s count field as the value. The leaf level items of TreeMap can be customized using leafItemSettings. leafItemSettings allows you to change properties such as fill, border, and labelPosition.

Apply color mapping

The color mapping feature supports customization of item colors based on the underlying value of item received from bound data source. Specify the field name from the values that have to be compared for the item in the equalColorValuePath or rangeColorValuePath property.

Enable legend

You can show legend for the TreeMap by setting the visible property to true in legendSettings object and injecting the TreeMapLegend module using the <Inject services={[TreeMapLegend]} />.

The tooltips are used when labels cannot display information due to space constraints. Tooltips can be enabled by setting the visible property to true in tooltipSettings object and injecting the TreeMapTooltip module using the <Inject services={[TreeMapTooltip]} />.
