+## Attributes
+
+### Line properties
+- `linecolor` sets the color of the lines. If you want to set the text color to the same value, you can also use `color=...`.
+- `linewidth=1.5` sets the width of the lines.
+- `instant_width=3.` sets the width of any instant gradients or pulses with respect to the `linewidth`.
+
+### Text properties
+- `textcolor` sets the color of the text. If you want to set the line color to the same value, you can also use `color=...`.
+- `font` sets whether the rendered text is :regular, :bold, or :italic.
+- `fontsize`: set the size of each character.
