How to use the dmsh.geometry function in dmsh

def test_circle(h0=0.7, show=True):
    geo = dmsh.geometry.Circle([0.0, 0.0], 1.0)
    X, cells = dmsh.generate(geo, h0, show=show)

    # X = numpy.column_stack([X[0], X[1], numpy.zeros(X.shape[1])])
    # import meshio
    # meshio.write_points_cells("out.vtk", X, {"triangle": cells})

    X = X.T

    assert numpy.array_equal(
        cells,
        [
            [3, 4, 6],
            [3, 5, 0],
            [5, 3, 6],
            [7, 4, 2],
            [4, 7, 6],
