Unfortunately, the generator messed up the formatting (a lot). Ping me if you need to discuss the suggested changes.

+## Description
+
+I want to extract point and line data from the signature created using the [SignaturePad](https://docs.telerik.com/devtools/maui/controls/signaturepad/overview) component of UI for .NET MAUI. The goal is to format the signature data as a string that represents the x, y coordinates of the strokes in the signature. Different formats for the output data are required, such as a custom format or an SVG-like format.
