mckinsey/vizro ? reverse-engineered prompt

Build me a polished Python app for exploring business data with interactive charts, tables, KPI cards, and filters. I want it to feel like a real dashboard product, not a rough prototype, with a clean layout, good default styling, and multiple pages or sections for different views of the data.

Make it easy to define the dashboard mostly from simple configuration, but still let me customize the charts, formatting, and interactions when needed. The app should support common things like dropdown filters, sliders, drill downs, and export options, and it should be straightforward to plug in Plotly charts and tabular views.

Please set it up so I can run it locally and then adapt it for production later. If you need to check the latest Vizro docs or examples online to match the current way this project is meant to work, go ahead and do that.
