<jupyter_start><jupyter_text>Andrews curves provides a mechanism for visualising clusters of multivariate data.Andrews curves have the functional form:    f(t) = x_1/sqrt(2) + x_2 sin(t) + x_3 cos(t) + x_4 sin(2t) + x_5 cos(2t) + ...Where *x* coefficients correspond to the values of each dimension and *t* islinearly spaced between *-pi* and *+pi*. Each row of frame then corresponds toa single curve.<jupyter_code>from bokeh.sampledata import iris
