Build Simple Interactive dashboard

SIMPLE PROJECT BUDGET OF $40

I am looking for a freelancer to help build a simple, lightweight interactive map dashboard that visualizes public data for a brain health & urban equity project.

Scope:
• Use existing NYC zip code-level data on noise, pollution, and cognitive risk factors (I will provide data sources or guidance).
• Build an interactive web-based map (example: Mapbox, Leaflet, or basic Google Maps API is fine) — does not need to be complex.
• Display basic overlays showing:
• Noise levels
• Pollution levels
• Cognitive risk score (simple calculated index)
• Basic hover or click tooltips showing zip code data.
• Simple, clear design (no advanced UI needed).
• Entire project should stay simple + lightweight, within a budget of $40.

Deliverables:
• Working basic map dashboard (hostable on a basic web page or GitHub Pages).
• Code files / instructions to run.
• Should run on desktop and mobile browsers.

Ideal skills:
• Basic experience with interactive maps (Mapbox, Leaflet, or similar).
• Basic JavaScript / HTML / CSS.
• Ability to deliver a clean, functional simple prototype — this is a non-commercial, civic project, so clarity > complexity.
