DreamPlot

Role

Designer and developer of a browser-based curve-fitting tool for student lab and coursework data analysis.

Challenge

Students often need to fit curves to experimental data without installing specialized software. Classroom tools should be immediate, visual, and export-ready for lab reports.

Approach

Built a lightweight, real-time canvas tool: enter or paste data, choose a model (linear through power law), drag points to refit instantly, predict X↔Y, and export PNG/CSV or a print-friendly report. No install, no build step for users.

Outcomes

A polished student-facing analysis tool suitable for lab workbook workflows and STEM courses that need quick model fitting and report-ready exports.

Overview

DreamPlot is a real-time, browser-based curve fitting tool designed for student data analysis. Learners plot points, visualize mathematical models, and extract best-fit equations directly in the browser.
