Tree visualization on a timeline for dataset derivations

Status: Just started

Aim

For applications where raw data is not supposed to be touched, data is repeatedly derived giving rise to a tree-like structure. Visualising the tree structure on a timeline is a useful tool for many organisations that process a lot of data.

Specifications

A tree should be provided as a json structure during initialization.

Tree Json format:

{
    "name": <node-name>,
    "date": <node-creation-date>,
    "image": <node-image-src>,
    "url": <node-url-if-any>,
    "owner": <owner-name-if-needed>,
    "children": [
        {
            "name": <node-name>,
            "date": <node-creation-date>,
            "image": <node-image-src>,
            "url": <node-url-if-any>,
            "owner": <owner-name-if-needed>,
            "children": [ {}, {}, {}]
        },
        {},
        {}
    ]
}

treevis's Issues

Show info on hover

Node should show some info on hovering the pointer on it. For example, name, owner, date, etc.

Scroll to zoom

Scrolling in should zoom into current cursor position, and scrolling out should zoom out.

Bonus: if Pinch in/out zoom can be implemented for interaction through a trackpad

Add image to node

Images should be shown inside nodes.

Bring nodes to front

Nodes go behind the area covered by bezier curves. They are visible because of the following css hack for .link:
fill: rgba(0,0,0,0);

This should solve:

• Lines over the nodes look ugly and should go behind the nodes
• Nodes are not clickable in certain areas
