User Engagement Dashboard Creation

I need a clean, web-based dashboard that focuses exclusively on user analytics, with special attention to engagement metrics. The goal is to let me open one screen and instantly understand how users interact with my product over time.

Key requirements
• Metrics: Any engagement-related figures I feed in (e.g., sessions per user, session duration, retention day-N) must be visualised.
• Visuals: Line charts are the primary format so trends can be spotted at a glance.
• Interactivity: Filters for date ranges and user segments will help me drill down quickly.
• Tech stack: I’m flexible—Tableau, Power BI, Looker Studio, Plotly/Dash, or a lightweight React + D3 setup all work for me, as long as the final result is responsive and easy to maintain.
• Data hookup: Connect to a simple CSV or a live SQL source; I just need clear instructions so I can swap in fresh data without breaking anything.

Acceptance criteria
1. The dashboard loads in under three seconds with sample data.
2. Each engagement metric is displayed in its own line chart that updates instantly when a filter is changed.
3. The project is delivered as a ready-to-run package with a brief walkthrough document (or short Loom video) explaining how to add new metrics and data sources.

If this sounds straightforward for you, let’s get it done.
