Interactive CSV Data Visualization Dashboard

I need a lightweight web-based dashboard that reads a CSV file and instantly turns the numbers into clear, interactive visuals. As soon as the dataset is loaded, I want to display:

• Line and pie charts for the key metrics
• A heatmap to spot patterns at a glance
• A sortable, searchable table of the raw data

Every visual must support hover tooltips so users can see precise values without cluttering the screen. No clicks, filters, or zooming are required right now—smooth hover interaction is enough.

Feel free to build with D3.js, Plotly, Chart.js, Dash, or another modern framework you’re comfortable with, as long as the final result works in any standards-compliant browser, looks clean on desktop and tablet, and can be hosted on a simple server.

Deliverables will be the complete, well-commented source code, a brief README explaining how to deploy it.
