About the Job We are looking for a creative developer to build a web page that shows charts and a map together. The page will display data second by second, and both the map and charts will move in sync with time. Work Details: Left Side (Map Section): Show a map with directions using latitude and longitude. A marker should move on the map according to the current second from the timeline. When the user hovers or moves the timeline scrubber, the marker should move to that second’s position. Right Side (Chart Section): Create a timeline scrubber that shows time in seconds. On hover, show a vertical line on all charts at that second. Display the data values (readings) of that second on the charts. There will be two types of charts: Analog chart: shows Min, Max, and Average values per second. Digital chart: shows 0 or 1 values per second. The map marker and charts must update together based on the selected second on the timeline. Skills Needed: Good knowledge of JavaScript and frontend frameworks like React or Vue. Experience with chart libraries (Recharts, Chart.js, or D3.js). Experience with map libraries (Leaflet, Mapbox, or Google Maps API). Understanding of real-time data and smooth UI updates.
