Creating a Timeline GUI

Hi, I am looking for a front end developer, who can provide a timeline GUI like in [login to view URL]: - The system needs to read a JSON values, and deploy to a timeline - User can zoom in to narrow down the time range (per day) See: label A in file attachment - User can zoom out to expand the time range (for example per 25 years) See: label A in file attachment - When user clicks on the plus icon, it can narrow down the time range, and use that chosen time as the center of the new time range. See: label B in file attachment - The system can show some timeline items bigger than the others at the same quarter. The bigger timeline items should be able to be set (not random). See: label C in file attachment It would be great if you can use or customize [login to view URL] or google charts to provide the above functionalities. However we strongly discourage the use of other people's javascript files with copyrights on it.
