create an interactive tree with D3js

I need this script modified as follows (or a blank project if preferred): [login to view URL] - nodes must be clickable and expand/collapse ([login to view URL]) - data can come from an external .json file OR a variable - when hovering on nodes, the route back to the first node must be highlighted with a customizable color ([login to view URL]) - the last nodes can have an optional parameter "link" and "target". When present, if I click that node the page redirects to that link (if target is empty or "parent") or opens a new window (if target is "blank") - points and lines must be customizable in size, color, transparency - data can be both a nested array ([login to view URL]) of flat data ([login to view URL]) - can specify if layout is vertical or horizontal ([login to view URL]) - can specify if layout is dendrogram or tidy tree ([login to view URL]) - can show values near labels for each node. The label will be in form of a decimal number between round brackets, must be red if <0, green if >0 or black if 0. Colors must be customizable in HEX values - must be drag and drop ([login to view URL]) - can be shown into an assignable container (a div with an ID) and adapt to (fill) the container - can use JQUERY - code must be supplied as files to be included (.css, .js, )
