Abstract

Methods and apparatus for visualizing a dataset are presented. For example, a method for visualizing a dataset includes identifying a first portion and at least a second portion of the dataset, forming a summary of the second portion of the dataset, and visualizing, on a display device, the first portion of the dataset and the summary of the second portion of the dataset. The summary is represented by one or more spatial shapes different from a spatial shape representative of the second portion before the formation of the summary. The identification of the first portion and the second portion, the formation of the summary, and the visualization of the first portion and the summary are implemented in accordance with a processor device associated with the display device.

Claims

identifying a first portion and at least a second portion of the dataset;

forming a summary of the second portion of the dataset; and

visualizing, on a display device, the first portion of the dataset and the summary of the second portion of the dataset;

wherein the summary is represented by one or more spatial shapes different from a spatial shape representative of the second portion before the formation of the summary; and

wherein the identification of the first portion and the second portion, the formation of the summary, and the visualization of the first portion and the summary are implemented in accordance with a processor device associated with the display device.

2. The method of claim 1, wherein identifying the first portion and the second portion of the dataset comprises:

presenting an initial visualization of the dataset on the display device; and

allowing selection of a first part of the initial visualization, wherein the first portion of the dataset corresponds to the first part of the initial visualization, and wherein the second portion of the dataset corresponds to at least part of the dataset other than the first portion of the dataset.

3. The method of claim 2, wherein formation of the summary occurs when a second part of the initial visualization corresponding to the second portion of the dataset is selectively moved out of view on the display device.

4. The method of claim 2, wherein allowing for selection of the first part of the initial visualization comprises allowing at least one of:

scrolling, magnification and demagnification of the initial visualization.

5. The method of claim 1, wherein the dataset is represented by at least one of:

a spatial representation, a map, geographical information, a graph, a graph of one or more processes, a graph comprising a plurality of data points, a two-dimensional visualization, a three-dimensional visualization, a multi-dimensional visualization, an organization chart, a network diagram, an architectural layout, a design visualization, and a visual representation.

6. The method of claim 1, wherein the summary comprises at least one of:

an abstraction of the second portion, a statistical summary of the second portion, a mathematical summary of the second portion, a histogram representative of the second portion, an indicator of position of at least one spatial feature of the second portion, and a summary of spatial features of the spatial shape representative of the second portion before the formation of the summary.

7. The method of claim 1, wherein an amount of information contained in the summary is less than an amount of information contained in the second portion of the dataset.

8. The method of claim 1, wherein the one or more spatial shapes have fewer spatial features than a number of spatial features of the spatial shape representative of the second portion before the formation of the summary, wherein a straight line segment, a curved line segment, and a bent line segment are spatial features.

9. The method of claim 1, wherein the one or more spatial shapes comprise at least one of:

a shape, a shape comprising a physical dimension according to a spatial shape representative of the second portion before the formation of the summary, a shape having a position according to a position of a spatial shape representative of the second portion before the formation of the summary, a rectangle, an annulus, a circular shape, a texture, a pattern, a color, an icon, a shading, a level of transparency, a glyph, an alpha-numeric character, and an icon that changes over time.

10. The method of claim 1, wherein the visualization of the first portion and the summary comprises the summary displayed in one or more summary visualization areas adjacent to a first portion visualization area.

11. The method of claim 1, wherein the one or more spatial shapes are different from a spatial shape representative of the second portion before the formation of the summary.

12. The method of claim 1 further comprising:

selecting one of the one or more spatial shapes, and

presenting data from the second portion of the dataset used to form the summary;

wherein the presenting of the data is performed in accordance with the selection of the one of the one or more spatial shapes.

13. The method of claim 12, wherein the selection of the one of the one or more spatial shapes comprises indicating the one of the one or more spatial shapes by a user controlled screen pointer.

14. The method of claim 12, wherein the presentation of the data provides at least one of:

statistical information associated with the data, mathematical information associated with the data, and a transformation of the data.

15. The method of claim 12, wherein the summary further summarizes at least part of the first portion of the dataset.

16. The method of claim 1, wherein the summary is visualized in spatial coordination with the first portion of the dataset.

17. The method of claim 1, wherein the summary comprises a context of the first portion.

18. Apparatus for visualizing a dataset, the apparatus comprising:

a memory; and

a processor coupled to the memory and configured to;

identify a first portion and at least a second portion of the dataset;

form a summary of the second portion of the dataset; and

visualize, on a display device, the first portion of the dataset and the summary of the second portion of the dataset;

wherein the summary is represented by one or more spatial shapes different from a spatial shape representative of the second portion before the formation of the summary.

19. The apparatus of claim 18, wherein identifying the first portion and the second portion of the dataset comprises:

presenting an initial visualization of the dataset on the display device; and

allowing selection of a first part of the initial visualization, wherein the first portion of the dataset corresponds to the first part of the initial visualization, and wherein the second portion of the dataset corresponds to at least part of the dataset other than the first portion of the dataset.

20. The apparatus of claim 19, wherein formation of the summary occurs when a second part of the initial visualization corresponding to the second portion of the dataset is selectively moved out of view on the display device.

21. The apparatus of claim 18, wherein the summary comprises at least one of:

an abstraction of the second portion, a statistical summary of the second portion, a mathematical summary of the second portion, a histogram representative of the second portion, an indicator of position of at least one spatial feature of the second portion, and a summary of spatial features of the spatial shape representative of the second portion before the formation of the summary.

22. The apparatus of claim 18, wherein an amount of information contained in the summary is less than an amount of information contained in the second portion of the dataset.
