Interactive Data‑Viz Prototype

Interactive Data‑Viz Prototype

The Challenge

Researchers sifted through gigabyte-scale CSVs and survey exports using Excel or ad-hoc Python scripts. Sharing findings meant pasting static screenshots into decks—a slow, error-prone loop that buried insights and frustrated non-technical collaborators.

The Solution

A browser-based app that streams huge datasets and lets users reshape charts on the fly—so researchers and admins can explore, refine, and present insights without installs or delays.

The Impact

  • Rapid storytelling: average “upload → final slide” time fell 2 days → 2 hours across pilot groups.
  • Reduced time to first chart (50k rows) from 18 min to 90 sec (‑92%)
  • Empowered non-technical stakeholders to uncover and communicate insights fast
  • One researcher shipped a conference poster in half a day instead of a week
