7bb2a342bfDescription This example demonstrates how to create complex diagrams combining geometric shapes with formatted multiline text. It showcases text wrapping, alignment, and positioning within various shapes. Key Features: Multiline text rendering with automatic word wrapping Text alignment (left, center, right) within shapes Integration of text with geometric shapes (rectangles, circles, polygons) Visual demonstration of text formatting and layout techniques Responsive text sizing and positioning Use Cases: Creating annotated diagrams and flowcharts Building educational materials with labeled shapes Generating technical documentation with visual aids Designing UI mockups with text elements
