I also didn't want the overhead of a full React frontend for a simple dashboard.</p> <p>The Solution: I built Morph-AI-Era, a monolithic app using:</p> <p>FastAPI (Backend): Handles CSV parsing (Pandas) and AI Forecasting (Scikit-learn).</p> <p>Vanilla JS + Plotly (Frontend): Fetches JSON and renders charts instantly.</p> <p>Supabase: For Auth and Credits.</p> <p>How it works:</p> <p>User drags CSV.</p> <p>FastAPI cleans NaN values and detects date columns.</p> <p>Frontend renders interactive Scatter/Line charts via Plotly.</p> <p>Bonus: I added a "Viral PDF" generator using html2canvas.</p> <p>The Result: A dashboard that feels like a SPA but runs on a simple Python backend. It handles 100k+ rows in the browser without lag.</p> <p>Try it out: I’m looking for feedback on the forecasting logic.
