<div id="docs"><p>Example of using the Draw interaction. Select a geometry type from the dropdown above to start drawing. To finish drawing, click the last point. To activate freehand drawing for lines and polygons, hold the <code>Shift</code> key. Square drawing is achieved by using Circle mode with a <code>geometryFunction</code> that creates a 4-sided regular polygon instead of a circle. Box drawing uses a custom <code>geometryFunction</code> that takes start and end point of a line with 2 points and creates a rectangular box.</p>
