for several elements, you can use the normal usage and replace the `draw()` method by the `innerdraw()`
75
+
76
+
```lua
77
+
mon_dessin = svg:create()
78
+
mon_dessin:addRect()
79
+
mon_dessin:addCircle()
80
+
mon_dessin:innerdraw()
81

```

result for `print(mon_dessin:innerdraw())` :

<rect y="10" x="10" stroke-width="1" height="10" width="10" rx="0" ry="0" />
