### Examples

```csharp
namespace AsposeCellsExamples
{
    using Aspose.Cells;
    using Aspose.Cells.Charts;
    using System;

    public class MapChartProjectionTypeDemo
    {
        public static void MapChartProjectionTypeExample()
        {
            // Create a new workbook
            Workbook workbook = new Workbook();

            // Add a new worksheet to the workbook
            Worksheet worksheet = workbook.Worksheets[0];

            // Add sample data to the worksheet for map chart
            worksheet.Cells["A1"].PutValue("Country");
            worksheet.Cells["A2"].PutValue("USA");
            worksheet.Cells["A3"].PutValue("Canada");
            worksheet.Cells["A4"].PutValue("Mexico");

            worksheet.Cells["B1"].PutValue("Value");
            worksheet.Cells["B2"].PutValue(100);
            worksheet.Cells["B3"].PutValue(80);
            worksheet.Cells["B4"].PutValue(60);

            // Add a map chart to the worksheet
            int chartIndex = worksheet.Charts.Add(ChartType.Map, 5, 0, 15, 5);
            Chart chart = worksheet.Charts[chartIndex];

            // Set the chart data range
            chart.SetChartDataRange("A1:B4", true);

            // Set the projection type for the map chart
            chart.NSeries[0].LayoutProperties.MapChartProjectionType = MapChartProjectionType.Mercator;

            // Output the projection type
            Console.WriteLine("Map Chart Projection Type: " + chart.NSeries[0].LayoutProperties.MapChartProjectionType);

            // Save the workbook
            workbook.Save("MapChartProjectionTypeExample.xlsx");
        }
    }
}
```
