General Tasks

PAIR WISE COMPARISONS OF TREES

Topological changes

Task
Menu/Tool Attributes
Effect
Did anything change, in general, or in a subtree. Were there small changes or major changes?
Visualization, Coordinates, BubleTree
Visualization, Colors map an extrinsic attribute on color
Visualization, Size map an extrinsic attribute on size
Comparison/Fast
Visualization, Coordinates Play with manual scaling
Nodes with same color seem to be similar others appear in different color and the scaling helps in finding changes.view
What nodes were added, deleted?
Visualization, Coordinates, Buble tree
Comparison/Fast
Search fast attribute=0
On each tree a selection of possible modified nodes (outlined in pink color) to be extracted. The process can be recursively issued on the new view.view
Did any node or subtrees "move" in the tree. Can you characterize those movements? Not yet Not yet

Attribute value changes

Task
Menu/Tool Attributes
Effect
Global impression: did things change a lot or not?
Visualization, Coordinates, Buble tree or Histogram
Visualization, Colors map extrinsic attribute with distribution algorithm
Visualization, Size map extrinsic attribute with distribution algorithm
Histogram shows variation in the distribution, Bubble gives an overview of the whole. No major changes.view
What nodes or subtrees changed the most Same algorithm than previous raws If there is big change in a subtree then the subtree will appear with a different drawing and/or a different color in the two views. In order explore, efficiently it is useful to run fast heuristic in order to only inspect the similar trees or run it recursively, if one want to inspect others.
Did the value of attribute XYZ for this node increase or decrease? in absolute terms, or relatively to other siblings or other nodes
Visualization, Coordinates, Buble tree
Visualization, Colors map XYZ attribute with distribution algorithm
Visualization, Size map XYZ attribute with linear algorithm
Visualization, Coordinates, Manual Play with manual
If some node have drastically changed (that surely what the user want to find), it will appear biggest in one tree. From this, select it and extract siblings, nodes with closed value, .... At any moment, explore the values of the selection with the detailed data menu. One can see the result on the first task of topologcal change.

GENERAL VISUALIZATION OF TREES

Topology

Task
Menu/Tool Attributes
Effect
Overall characteristics: How large is the tree? How many levels deep? What is the deepest branch? Does the depth vary between subtrees or not?
Detailed Data Intrinsic attributes
At any moment, such informations can be obtained for any subtree (readme), view.
Path: What is the path of this node ? Local relatives : what are the children, siblings or cousins of this node?
Search/Advanced Special Options
The path, children, or ..... appear oulined in pink, view
Filtering by level: e.g. show me only the first level, or show only 3 levels down, or removes all the leaves
Search Intrinsic attributes depth and/or hight
The subtree appears oulined in pink, view
Topologies question that involve counting nodes can be seen as attribute dependant questions: e.g. Which branch contains the largest number of nodes? or Which branch has the largest fan-out?
Search/advanced Search root option
Search/advanced Intrinsic attribute arity or node
The branchs appear oulined in pink view

Attribute based

Task
Menu/Tool Attributes
Effect
Find nodes with high values of a numerical attribute X ?
Search/advanced Attribute X, move the cursor at the top position
The nodes appear oulined in pink, view
Find nodes with given value of a numerical attribute X ? Find nodes with value Y of categorical attribute X
Search Attribute X, fix the regular expression
The nodes appear oulined in pink, same than previous using "=" operator, no view is given, see also the video.
What value of a categorical attribute occurs more often? e.g. Are there more farm animals or pets ? Not yet Not yet
Find nodes with certain values of two or more attributes e.g. what video file is used the most
Visualization, Colors, RGB Map extrinsic numerical attribute linear
Search Extrinsic categorical attributes (example label)
The nodes will appear with dark color and outlined in pink. It is up to the user to extract a new view.view
Number of nodes in a tree, or subtree? e.g. How many animal?, how many mammals? Comparison of branches of the tree (i.e. subtrees with most nodes)? Is there more mammals or fish? Largest fanout e.g. What is the largest group of animals with same lineage?
Visualization, Colors, HSV Map intrinsic attribute arity by distribution algorithm
Visualization, Sizes Map intrinsic attribute node
Search, advanced option play with the cursor in high position for node, arity, common name and Latin name.
Detailed data
The bigest nodes are the root of the biggest subtrees, the violet one have the largest fan out. Inspect the value by filtering in the detailed Data menu.view

Known items

Task
Menu/Tool Attributes
Effect
Which node(s) has a label containing this string? e.g. find "giraffe" in a tree of animals
Search Attribute label, fix the regular expression (e.g. "giraffe")
The nodes appear oulined in pink. This can be down for several extrinsic attributes with operators, see the video.
Locate a node knowing its path. Go back to a node you have visited before. not yet not yet

Labeling

Task
Menu/Tool Attributes
Effect
Review all the labels in a subtree
Search select and extract the subtree
Detailed data explore labels in the new view.
View display all the labels of the subtree. Allready shown in the previous tasks. See also the video.

Browsing

Task
Menu/Tool Attributes
Effect
Explore the tree by performing a series of up and downs in the tree e.g. you are looking for a cute animal... so you look into mammals, then primates, then gorillas, and chimpanzees, but you realize that are not that cute, so you go to felines, to tigers and cheetahs, but now remember that pandas are your favorites and you go there. not yet not yet

Managing the analysis

Task
Menu/Tool Attributes
Effect
Marking nodes of interest, removing special anomalies.
Search select the nodes
Visualization, shape filter and change the shape nodes.
The view has some marked nodes with special shape.view
Saving visualizalization settings for future reference.
File Save in TLP format
A file containing all the loaded or created view.
Keeping the histoy of your analysis, reviewing it and replaying it with different parameters. not yet not yet
