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
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.
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
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
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
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.
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

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.
