How to customize the WinForms TreeMap label font style and label text alignment?

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        TreeMap1.ItemsSource = data.PopulationDetails;
        TreeMapFlatLevel treeMapFlatLevel1 = new TreeMapFlatLevel();
        treeMapFlatLevel1.GroupPath = "Continent";
        TreeMap1.Levels.Add(treeMapFlatLevel1);
        TreeMap1.LeafItemSettings.LabelPath = "Country";
    }
}

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        TreeMap1.ItemsSource = data.PopulationDetails;
        TreeMap1.LeafItemDrawing += TreeMap1_LeafItemDrawing;
    }
    void TreeMap1_LeafItemDrawing(object sender, LeafItemDrawingEventArgs e)
    {
        e.Cancel = true;
        StringFormat drawFormat = new StringFormat() { Alignment = StringAlignment.Center, LineAlignment = StringAlignment.Center };
        e.Graphics.FillRectangle(e.Color, e.RectSize);
        e.Graphics.DrawRectangle(new Pen(new SolidBrush(Color.White), 1), e.RectSize);
        var font = new Font("Segoe UI", 18F, FontStyle.Regular, GraphicsUnit.Pixel, ((byte)(0)));
        e.Graphics.DrawString(e.Label, font, TreeMap1.LabelBrush, e.RectSize, drawFormat);
    } 
}
