USolver includes powerful tools for creating custom shapes, allowing users to draw freely by placing points one by one. You can define straight edges, curves, and even add helper points to guide the shape’s structure and behavior. These custom shapes are highly interactive and can be linked directly to spreadsheet cells, enabling dynamic updates and data-driven visualizations. This makes it easy to build complex, responsive diagrams tailored to specific use cases, all while maintaining a clear connection between visuals and data.
