Ready to dive in? Let’s start building your interactive EV dashboard with .NET MAUI!

## Step 1: Designing the dashboard layout

Start by creating a clean and responsive geo-analytics workspace using a Grid layout in .NET MAUI. This layout organizes the dashboard components logically, ensuring an intuitive user experience.

Here’s how you can do it in XAML code:

```
<ScrollView Orientation="Vertical">
    <Grid RowDefinitions="Auto, Auto" ColumnDefinitions="*">

        <!-- Header -->
        <Grid Grid.Row="0">
            <!-- Logo + Title -->
        </Grid>

        <!-- Body -->
        <Grid Grid.Row="1" ColumnDefinitions="2*, *, *" ColumnSpacing="16">

            <!-- Left Column -->
            <VerticalStackLayout Grid.Column="0">
                <Border>
                    <!-- SfMaps: EV Adoption -->
                </Border>
                <Border>
                    <!-- KPIs: Battery, Plug-in, Growth -->
                </Border>
            </VerticalStackLayout>

            <!-- Middle Column -->
            <VerticalStackLayout Grid.Column="1">
                <Border>
                    <!-- SfCartesianChart: EV Trend -->
                </Border>
                <Border>
                    <!-- SfCircularChart: Radial Bar (EV Mix) -->
                </Border>
            </VerticalStackLayout>

            <!-- Right Column -->
            <VerticalStackLayout Grid.Column="2">
                <Border>
                    <!-- SfCircularChart: Continent Share -->
                </Border>
                <Border>
                    <!-- SfCircularChart: Country Share -->
                </Border>
            </VerticalStackLayout>
        </Grid>
    </Grid>
</ScrollView>
```

## Step 2: Implementing MVVM architecture

The **MVVM** (Model-View-ViewModel) architecture is essential for building scalable, testable, and maintainable .NET MAUI dashboards. It separates the UI (** View**) from the business logic (** ViewModel**) and data (** Model**).

### Creating model classes for EV data

You can define model classes to structure your EV data, including country stats, yearly trends, and EV mix slices.

Here’s how the C# code example to achieve this:

```
public class EvAdoptionRecord
{
    // Raw EV adoption record from CSV (per country, per year)
}

public class CountryAdoptionSnapshot
{
    // Latest-year snapshot per country
}

public class TopCountryShare
{
    // Top N countries by Battery EV share
}

public class ContinentShare
{
    // Aggregated Battery EV share by continent
}

public class YearlySharePoint
{
    // Single point in yearly trend series (Year, Value)
}

public class PowertrainMixSlice
{
    // Slice in radial bar (Battery / Plug-in / Other)
}
```

**Note:** You can check the complete implementation of the **Model** classes on the [Github](https://github.com/SyncfusionExamples/Essential-Guide-to-Creating-a-Real-Time-Geo-Analytics-Dashboard-Using-.NET-MAUI--Charts-and-Maps/blob/master/GeoAnalyticsDashboard/GeoAnalyticsDashboard/Models/Models.cs)
 repository.

### Building the ViewModel for dynamic updates

The **ViewModel** loads the CSV data, processes the latest year’s shares, and then updates all relevant properties dynamically when a user selects a new country on the map. It manages observable collections that the UI binds to, ensuring seamless updates.

Explore the full `DashboardViewModel` implementation in C#:

```
public class DashboardViewModel
{
    public void LoadCsvData(string path)
    {
        // implementation for loading CSV
    }

    public void ApplySelection(CountryEvStat cs)
    {
        // implementation for updating UI data based on selection
    }
}
```

**Note:** For more details, refer to the `DashboardViewModel`class on [Github](https://github.com/SyncfusionExamples/Essential-Guide-to-Creating-a-Real-Time-Geo-Analytics-Dashboard-Using-.NET-MAUI--Charts-and-Maps/blob/master/GeoAnalyticsDashboard/GeoAnalyticsDashboard/ViewModels/ViewModels.cs)
.

## Step 3: Building modular views with user controls

A well-structured dashboard is modular. Each section delivers distinct, actionable insights. By using **user controls in .NET MAUI**, you can keep your code clean, reusable, and easy to maintain.

### Visualizing EV adoption by country

Start with a **world map** that visually represents EV adoption. Countries are color-coded based on their share of Battery EVs, making hotspots easy to identify. Users can interact by selecting a country, which triggers dynamic updates across the dashboard.

Explore the full XAML implementation for the map layout**:**

```
<map:SfMaps Grid.Row="1">
    <map:SfMaps.Layer>
        <map:MapShapeLayer x:Name="ShapeLayer" DataSource="{Binding Countries}" ShapeDataPrimaryValuePath="Name" ShapeColorValuePath="BatteryShare" EnableSelection="True" ShowShapeTooltip="True" ShapeSelected="MapShapeLayer_SelectionChanged"... >
            <!-- Color ranges and Legend -->
        </map:MapShapeLayer>
    </map:SfMaps.Layer>
</map:SfMaps>
```

![Interactive world map showing EV adoption by country](https://www.syncfusion.com/blogs/wp-content/uploads/2026/01/image004-1.png)

Interactive world map showing EV adoption by country

When a user selects a country, the dashboard updates in real time. KPIs, EV trend charts, radial bar mix, and pie charts all reflect the selected country’s data without manual refresh.

**Note:** You can check MAUI Map’s selection [documentation](https://help.syncfusion.com/maui/maps/selection)
 for more insights.

### Displaying key performance indicators (KPIs)

Now, we need to display critical metrics, such as Battery EV share, Plug-in share, and Year-over-Year growth, in a responsive KPI card. These values update instantly when a country is selected.

Add this to your project:

```
<!-- KPI Card (updates on country selection) -->
<Border Padding="16">
    <HorizontalStackLayout Spacing="16">

        <!-- Battery Share -->
        <VerticalStackLayout>
            <Label Text="Battery Share" />
            <Label Text="{Binding SelectedBatteryShare, StringFormat='{0:F2}%'}" />
        </VerticalStackLayout>

        <!-- Plug‑in Share -->
        <VerticalStackLayout>
            <Label Text="Plug‑in Share" />
            <Label Text="{Binding SelectedPlugInShare, StringFormat='{0:F2}%'}" />
        </VerticalStackLayout>

        <!-- Growth YoY -->
        <VerticalStackLayout>
            <Label Text="Growth YoY" />
            <Label Text="{Binding SelectedGrowth, StringFormat='{0:F2}%'}" />
        </VerticalStackLayout>

    </HorizontalStackLayout>
</Border>
```

### Representing EV powertrain mix

Use a [Radial Bar Chart](https://help.syncfusion.com/maui-toolkit/circular-charts/radialbarchart)
 to display the EV powertrain mix, like Battery EV, Plug-in Hybrid, and Other, for the selected country. This visualization helps users quickly understand market composition.

Code example for quick integration:

```
<Grid Grid.Row="1"
      HorizontalOptions="Center"
      VerticalOptions="Start"
      Padding="0">
    <chart:SfCircularChart HeightRequest="250">
        <chart:RadialBarSeries ItemsSource="{Binding SelectedMix}" ShowDataLabels="True" LabelContext="Percentage" XBindingPath="Name" YBindingPath="Value" InnerRadius="0.35" EnableTooltip="True" EnableAnimation="True">
        </chart:RadialBarSeries>
           <chart:SfCircularChart.Legend>
               <chart:ChartLegend Placement="Right" />
           </chart:SfCircularChart.Legend>
    </chart:SfCircularChart>
</Grid>
```

### Analyzing EV adoption trends over time

You can use a [Line Chart](https://help.syncfusion.com/maui-toolkit/cartesian-charts/line)
 to illustrate how the shares of Battery EVs and Plug-in Hybrids have changed over the years for the selected country. This trend analysis highlights growth patterns and market shifts.

Below is the code you need:

```
<!-- Two LineSeries: BatterySeries, PlugInSeries -->
<chart:SfCartesianChart>
    <chart:SfCartesianChart.XAxes>
        <chart:CategoryAxis />
    </chart:SfCartesianChart.XAxes>

    <chart:SfCartesianChart.YAxes>
        <chart:NumericalAxis />
    </chart:SfCartesianChart.YAxes>

    <chart:LineSeries ItemsSource=“Binding BatterySeries}" XBindingPath="Year" YBindingPath="Value" />
    <chart:LineSeries ItemsSource=“Binding PlugInSeries}" XBindingPath="Year" YBindingPath="Value" />
</chart:SfCartesianChart >
```
