JotForm Widgets: Editable diagram

Is there a way to allow a client to add to a diagram within the form?

I would like to add a line drawing of a dog and have the client indicate on the drawing (with an 'x' or circle) the area of needed treatment.

Hi,

Thank you for contacting us.
There are a couple of widgets that allow you to let the users draw on pictures;

1. Draw on Image Widget
The widget will let you link a URL to an image, and your users can draw on the picture when filling in the form.

2. Annotate Picture
The widget will let you upload a picture, and the users can draw freely on the image.
