Using Dash by Plotly for Interactive Visualisation of Crime Data

on YouTube ↗29m

" summary

Uses Dash and plotly express with pandas and Flask to build an interactive homicide dashboard from a public CSV, wiring dropdowns to graphs via Dash callbacks and rendering Plotly figure objects. Live demo shows faceting, theming for presentation, and marker modes. Claims rapid prototyping but reports multi-page routing awkwardness, heavy client JS causing slow render in virtual desktops, and production deployment via Gunicorn; team ultimately moves to hand‑rolled JavaScript charts for performance.
