Multidimensional structured data visualization method and apparatus, text visualization method and apparatus, method and apparatus for visualizing and graphically navigating the world wide web, method and apparatus for visualizing hierarchies
A method of displaying correlations among information objects includes receiving a query against a database; obtaining a query result set; and generating a visualization representing the components of the result set, the visualization including one of a plane and line to represent a data field, nodes representing data values, and links showing correlations among fields and values. Other visualization methods and apparatus are disclosed.
1. A method of visualizing a hierarchy, the method comprising: receiving a plurality of data records of a hierarchy that has a plurality of nodes, wherein a node includes at least zero data records and at least zero other nodes, the data records each including a field that identifies the position of the record in the hierarchy; displaying a plurality of levels to represent the hierarchy, the displaying including displaying a glyph to represent a node of each branch of the hierarchy, radially arranging nodes that are at a common level in the hierarchy, and connecting nodes to portray hierarchical relationships; selectively labeling at least some of the nodes; and displaying records that terminate at a given node as glyphs arranged on a pan located beneath the node at which the records terminate.
2. A method of visualizing a hierarchy in accordance with claim 1 wherein a node having another node defines a subtree, the method further comprising lowering a first subtree relative to a second subtree when the first subtree is larger than the first subtree, the first and second subtrees being below a common node.
3. A method of visualizing a hierarchy in accordance with claim 1 wherein radially arranging nodes comprises selecting a radius depending on the number of nodes of be radially arranged.
4. A method of visualizing a hierarchy in accordance with claim 1 and further comprising color coding a glyph representing a record depending on a property of the record.
5. A method of visualizing a hierarchy in accordance with claim 1 and further comprising color coding a glyph representing a node depending on a property of the node.
6. A method of visualizing a hierarchy in accordance with claim 1 and further comprising shape coding a glyph representing a record depending on a property of the record.
7. A method of visualizing a hierarchy in accordance with claim 1 and further comprising shape coding a glyph representing a node depending on a property of the node.
8. A method of visualizing a hierarchy, the method comprising: receiving a plurality of data records of a hierarchy that has a plurality of nodes, wherein a node includes at least zero data records and at least zero other nodes, wherein a node having another node defines a subtree, the data records each including a field that identifies the position of the record in the hierarchy; displaying a plurality of levels to represent the hierarchy, the displaying including displaying a glyph to represent a node of each branch of the hierarchy, radially arranging nodes that are at a common level in the hierarchy, and connecting nodes to portray hierarchical relationships, the displaying including lowering a first subtree relative to a second subtree when the first subtree is larger than the first subtree, the first and second subtrees being below a common node; and selectively labeling at least some of the nodes.
9. A method of visualizing a hierarchy in accordance with claim 8 wherein radially arranging nodes comprises selecting a radius depending on the number of nodes of be radially arranged.
10. A method of visualizing a hierarchy in accordance with claim 8 and further comprising selectively color coding a glyph.
11. A method of visualizing a hierarchy in accordance with claim 8 and further comprising selectively shape coding a glyph.
12. A computer readable medium embodying computer program code which, when loaded in a computer, causes the computer, in operation, to:
receive a plurality of data records of a hierarchy that has a plurality of nodes, wherein a node includes at least zero data records and at least zero other nodes, the data records each including a field that identifies the position of the record in the hierarchy; display a plurality of levels to represent the hierarchy, the displaying including displaying a glyph to represent a node of each branch of the hierarchy, radially arranging nodes that are at a common level in the hierarchy, and connecting nodes to portray hierarchical relationships, wherein the computer program code is further configured to selectively label at least some of the nodes; and display records that terminate at a given node as glyphs arranged on a pan located beneath the node at which the records terminate.
13. A computer readable medium in accordance with claim 12 wherein a node having another node defines a subtree, and wherein the computer program code is further configured to lower a first subtree relative to a second subtree when the first subtree is larger than the first subtree, the first and second subtrees being below a common node.
14. A computer readable medium in accordance with claim 12 wherein radially arranging nodes comprises selecting a radius depending on the number of nodes of be radially arranged.
15. A computer readable medium in accordance with claim 12 wherein the computer program code is further configured to selectively color code a glyph.
16. A computer readable medium in accordance with claim 12 wherein the computer program code is further configured to selectively shape code a glyph.
