Data Input and Cell Referencing in Spreadsheet View

This example demonstrates how to input data and refer to cells in GeoGebra's Spreadsheet View, enabling dynamic links between tabular data and geometric objects or functions. The core mathematical concepts include data organization, variable assignment, and cell referencing (e.g., A1, B2) in mathematical modeling. The construction focuses on using the spreadsheet view to directly enter values or formulas and referencing cells to create dynamically updated points, lists, or functions without additional commands. It is suitable for middle school and above students learning data-driven geometry or function graphing, and for teachers demonstrating the linkage between data and graphical representations.
