Interactive Data Analysis Web Platform -- 2

I need a browser-based platform that lets me load raw datasets, run meaningful analyses, and explore the results through dynamic, JavaScript-driven visuals. Data analysis is the heart of the job, yet I want the findings displayed in a modern web interface and, where it adds value, enhanced with lightweight 3D animations (think Three.js or similar) so patterns leap off the screen.

Here is the flow I imagine:
• Securely ingest CSV, JSON, or API-pulled data.
• Perform statistical or exploratory analysis inside a well-structured codebase (Python on the back end or pure JS with Web Workers—open to your preferred stack).
• Render interactive charts, maps, or models directly in the browser; if a 3D view clarifies insights, integrate it smoothly.
• Package the whole solution in clean, documented code that I can host on a standard web server.

Acceptance criteria
– Accurate, reproducible analytical results on a sample dataset I provide.
– Responsive UI that performs well on desktop and mobile.
– Modular code with comments and a concise README explaining setup and extending the analysis pipeline.
– Brief hand-off call or screen-share for walkthrough.

When you respond, focus on your relevant experience building data-driven web tools, especially any work where complex analytics and visualisation intersect. Links or short clips of a live dashboard or similar project will help me gauge fit quickly.
