Hi everyone Please place bid after check the requirements. I have an old US Map website source code. 1. Objective Improve the existing US map visualization website so that users can: Clearly visualize all US states. Select and highlight individual states. View state-specific information. Understand data through color-coded map regions. Search for states quickly. Zoom and pan naturally. View responsive map layouts on desktop, tablet, and mobile. Easily distinguish selected, hovered, and unselected states. Handle missing or unavailable data gracefully. 2. Main Map Requirements US map The application should display a complete map of the 50 US states. Each state should: Have a unique geographic boundary. Be selectable/clickable. Support hover interaction. Have a visually distinct selected state. Display appropriate data-driven coloring where applicable. The map should not be implemented as a collection of manually positioned HTML elements. Use geographic data such as GeoJSON/TopoJSON and render the actual state boundaries. 3. Map Interaction Hover When the user moves the mouse over a state: Highlight the state. Show a tooltip. Display the state's name. Display the relevant visualization value/data. Junior or Senior US candidates preferred. Best regards

Hi, I can enhance the existing US map visualization website to ensure users can interact with the map intuitively and effectively. This involves implementing a dynamic map using GeoJSON or TopoJSON to accurately render state boundaries, which will significantly improve user experience. I will focus on ensuring that each state is clearly selectable and that hover interactions provide immediate feedback, such as tooltips displaying state names and relevant data. Additionally, I will implement responsive layouts to ensure the map functions seamlessly across devices, from desktops to mobile phones. To get started, I will need access to the existing source code and any specific data you want to visualize on the map. It would also be helpful to understand any design preferences you have for the color-coding and tooltip information. I will test the implementation by verifying the responsiveness of the map, ensuring that all interactions work as intended, and confirming that the data displays correctly for each state. I will also check how the application handles missing data to ensure a smooth user experience. You can view my portfolio here: https://www.freelancer.com/u/techplusintl Thanks!

Hi, You’re not just asking for a map update , you’re looking to turn an old visualization into something users can trust at a glance. I can help modernize the US map so every state has accurate GeoJSON/TopoJSON boundaries, smooth hover/select states, responsive behavior, tooltips, search, zoom/pan, and clean handling for missing data. I’ve worked on similar PHP/JavaScript and frontend mapping interfaces, including data-driven UI updates and responsive layouts. I’ll review your current source, identify what can be reused, and improve the rendering layer so the map feels precise, fast, and easy to understand across desktop and mobile. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you want, I can start by auditing the current code and outlining the quickest path to a polished result. Would you prefer the map to use a specific data source or API for state values, or should I wire in the existing dataset? Best regards, Asad

The 50-state map should use real GeoJSON boundaries, not positioned HTML shapes. I’d first review the old source and its data format, then replace or repair the map layer without disrupting working parts. Each state will support hover, click selection, tooltips, data-driven colors, search, and clear missing-data states. I’ll also keep selected and hovered styles separate so interactions remain clear during zoom and pan. The first milestone can be a responsive 50-state map with working hover and selection in 2 days, released only after it works. Which framework or map library does the current source use?
