Providing an ellipsoid having a characteristic based on local correlation of attributes

An article comprising at least one non-transitory storage medium storing instructions that upon execution cause a system to:

• group data records into clusters according to attributes of the data records, the attributes to be correlated;
• merge the clusters based on a proximity criterion to produce corresponding partitions, wherein a number of the partitions is less than a number of the clusters;
• create ellipsoids that represent corresponding ones of the partitions for presentation in a scatter plot visualization;
• and
• adjust respective characteristics of the ellipsoids dependent upon corresponding local correlations between the attributes of the data records represented by corresponding ones of the partitions, wherein the adjusting comprises adjusting a rotation angle of a particular one of the ellipsoids based on whether the corresponding local correlation is a positive correlation or a negative correlation, wherein a first rotation angle of the particular ellipsoid corresponding to the positive correlation results in a dimension of the particular ellipsoid having a positive slope, and wherein a second rotation angle of the particular ellipsoid corresponding to the negative correlation results in a dimension of the particular ellipsoid having a negative slope.

A system comprising:

• at least one storage medium to store data records;
• and
• at least one processor to:
• group the data records into clusters according to attributes of the data records, the attributes to be correlated;
• merge at least two clusters that satisfy a proximity criterion;
• create at least one ellipsoid for presentation in a scatter plot visualization based on the grouping and merging, the ellipsoid including pixels representing multiple corresponding data records, wherein the ellipsoid has characteristics that are based on a corresponding local correlation of the attributes of the data records represented by the ellipsoid;
• and
• adjust at least one of the characteristics of the ellipsoid based on a direction of the local correlation, wherein adjusting at least one of the characteristics of the ellipsoid comprises adjusting a rotation angle of the ellipsoid based on whether the local correlation is a positive correlation or a negative correlation, wherein a first rotation angle of the ellipsoid corresponding to the positive correlation results in a dimension of the ellipsoid having a positive slope, and wherein a second rotation angle of the ellipsoid corresponding to the negative correlation results in a dimension of the ellipsoid having a negative slope.
