# Introducing the New .NET MAUI TreeMap Control
[Karthik Raja Arumugam](https://www.syncfusion.com/blogs/author/karthik-raja-arumugam)
**TLDR:** Exploring the user-friendly features of the new Syncfusion .NET MAUI TreeMap control and the steps to integrate it in a .NET MAUI application.
We are delighted to introduce another data visualization control in the [Syncfusion .NET MAUI suite](https://www.syncfusion.com/maui-controls)
for the [2024 Volume 1](https://www.syncfusion.com/forums/187257/essential-studio-2024-volume-1-main-release-v25-1-35-is-available-for-download)
release, the all-new [.NET MAUI TreeMap](https://www.syncfusion.com/maui-controls/maui-tree-map)
control.
The .NET MAUI TreeMap control visually represents hierarchical data using nested rectangles, sized and colored based on underlying values. It efficiently displays grouped and nested data structures, offering extensive customization options and supporting item selection.
In this blog, we’ll delve into the key features of the .NET MAUI TreeMap and outline the steps to get started!
## Key features
The .NET MAUI TreeMap Control provides support for the following key features:
- [Data binding](#Data)
- [Layout types](#Layout)
- [Levels](#Levels)
- [Legend](#Legends)
- [Tooltip](#Tooltips)
- [Brush settings](#Brush)
- [Selection](#Selection)
- [Appearance customization](#Appearance)
Let’s take a closer look at these features!
### Data binding
The .NET MAUI TreeMap control seamlessly binds hierarchical data structures, visually representing the data into groups with leaf items as rectangles, providing precise data representation.

### Layout types
The .NET MAUI TreeMap control offers multiple layout types to organize hierarchical data effectively. The layout types include **squarified**, ** slice and dice horizontal**, ** slice and dice vertical**, and ** slice and dice auto**.
| Squarified layout | Slice and dice horizontal layout | Slice and dice vertical layout |
| --- | --- | --- |
**Different layout types *in the .NET MAUI TreeMap control***
Based on the high aspect ratio, the **slice and dice auto** layout visualizes the .NET MAUI TreeMap in long, thin rectangles vertically or horizontally.
### Levels
The .NET MAUI TreeMap control seamlessly integrates multiple hierarchical data levels for richer and more detailed visualizations.

### Legends
You can use legends to add additional information for interpreting a TreeMap with various colors, shapes, and more.

### Tooltips
When the mouse hovers over items, the interactive TreeMap displays the details about the items’ values in tooltips.

### Brush settings
Brush settings customize the fill colors for leaf items based on ranges or values. There are four brush settings available:
- **UniformBrushSettings,**
- **RangeBrushSettings,**
- **DesaturationBrushSettings,**
- **PaletteBrushSettings**.
Each setting provides unique options for defining and applying color schemes, enhancing the TreeMap visualization.
| Uniform brush | Range brush |
| --- | --- |
| Desaturation brush | Palette brush |

## Getting started with the .NET MAUI TreeMap control
We have explored the key features of the .NET MAUI TreeMap control. Let’s see how to integrate the control in your .NET MAUI app.
### Step 1: Create a new .NET MAUI app
Open [Visual Studio](https://visualstudio.microsoft.com/)
and [create a new .NET MAUI application](https://learn.microsoft.com/en-us/dotnet/maui/get-started/first-app?view=net-maui-7.0&tabs=vswin&pivots=devices-android)
.
### Step 2: Add the required NuGet package
Syncfusion .NET MAUI components are available in the [NuGet Gallery](https://www.nuget.org/)
. To add the **SfTreeMap** to your project, open the ** NuGet package manager** in Visual Studio and search for [Syncfusion.Maui.TreeMap](https://www.nuget.org/packages/Syncfusion.Maui.TreeMap)
, and install it.
### Step 3: Import and initialize the .NET MAUI TreeMap control
Now, add the **Syncfusion.Maui.TreeMap** namespace to your XAML page, and initialize the ** SfTreeMap** control.
Refer to the following code example.
```
xmlns:treemap="clr-namespace:Syncfusion.Maui.TreeMap;assembly=Syncfusion.Maui.TreeMap"
```
### Step 4: Register the Syncfusion core handler
Then, register the Syncfusion core handler in the **MauiProgram.cs** file.
```
using Syncfusion.Maui.Core.Hosting;
public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder.ConfigureSyncfusionCore();
}
}
```
### Step 5: Populate the TreeMap data source
Let’s create a **model** class and ** view model** data using the actual data. Then, bind the ** DataSource** of TreeMap to the XAML page.
**Creating a model class**
```
public class PopulationDetails
{
public string Country { get; set; }
public string Continent { get; set; }
public int Population { get; set; }
}
```
**Create a view model data with the actual data**
```
public class PopulationViewModel
{
public PopulationViewModel()
{
this.PopulationDetails = new ObservableCollection()
{
new PopulationDetails() { Continent ="North America", Country = "United States of America", Population = 339996564 },
new PopulationDetails() { Continent ="South America", Country = "Brazil", Population = 216422446 },
new PopulationDetails() { Continent ="North America", Country = "Mexico", Population = 128455567 },
new PopulationDetails() { Continent ="South America", Country = "Colombia", Population = 52085168 },
new PopulationDetails() { Continent ="South America", Country = "Argentina", Population = 45773884 },
new PopulationDetails() { Continent ="North America", Country = "Canada", Population = 38781292 },
new PopulationDetails() { Continent ="South America", Country = "Peru", Population = 34352719 },
new PopulationDetails() { Continent ="South America", Country = "Venezuela", Population = 28838499 },
new PopulationDetails() { Continent ="South America", Country = "Chile", Population = 19629590 },
new PopulationDetails() { Continent ="South America", Country = "Ecuador", Population = 18190484 },
new PopulationDetails() { Continent ="North America", Country = "Guatemala", Population = 18092026 },
new PopulationDetails() { Continent ="South America", Country = "Bolivia", Population = 12388571 },
new PopulationDetails() { Continent ="North America", Country = "Honduras", Population = 10593798 },
new PopulationDetails() { Continent ="North America", Country = "Nicaragua", Population = 7046311 },
new PopulationDetails() { Continent ="South America", Country = "Paraguay", Population = 6861524 },
new PopulationDetails() { Continent ="North America", Country = "El Salvador", Population = 6364943 },
new PopulationDetails() { Continent ="North America", Country = "Costa Rica", Population = 5212173 },
new PopulationDetails() { Continent ="South America", Country = "Uruguay", Population = 3423109 },
};
}
public ObservableCollection PopulationDetails { get, set, }
}
```
**Bind the DataSource of TreeMap**
```
```
Now, you can run the application and visualize the specified data in the .NET MAUI TreeMap control.
