Heatmap With Custom Mesh

GraphingLib components used: Figure, Heatmap

# Create data on a non-uniform grid with logarithmic spacing
x_nonuniform = np.logspace(0, 2, 30)  # Log-spaced: 1 to 100
y_nonuniform = np.logspace(-1, 1, 25)  # Log-spaced: 0.1 to 10

# Create mesh grids
x_mesh, y_mesh = np.meshgrid(x_nonuniform, y_nonuniform)

# Create some sample data
z_data = np.sin(np.log10(x_mesh)) * np.cos(np.log10(y_mesh))

# Create heatmap with custom mesh (uses pcolormesh internally)
