Building a Modern Dashboard with Flask and Chart.js

Dashboards are the first thing users open every morning, so they need to load fast and communicate clearly. In this post we walk through structuring stat cards, choosing chart types, and keeping the UI responsive on mobile.

Keep widgets independent

Each widget should fetch its own data and fail gracefully on its own, so one slow query doesn't freeze the whole page.
