Image to Desmos Graph Converter

This tool converts a raster image input into Desmos-compatible graph data, enabling educators, students, and researchers to translate visual information into mathematical representations. It targets users who want to analyze, teach, or illustrate patterns by exporting to Desmos format rather than manual plot construction. When to use: classroom demonstrations of image-driven functions, data visualization projects, or rapid ideation of graph-based mappings from imagery.
The system accepts an image file, performs pixel sampling at a defined density, and maps pixels to graph coordinates. It then generates Desmos-ready constructs (points, curves, or piecewise representations) and exports in Desmos-compatible syntax. Required features include image ingestion, density control, color-to-graph mapping, and export to Desmos-compatible data. Optional features include grayscale thresholding, color-based segmenting, and batch processing for multiple images.
Outputs can be pasted into Desmos or saved as a file. The tool emphasizes accuracy and reproducibility across images, and it accommodates a range of educational contexts from quick demonstrations to formal assignments.
The architecture supports future extensions such as alternative coordinate mappings or integration with notebook workflows, while preserving a simple input/output contract.
