The table lists each region that is desired or present in the current diagram along with the desired and actual proportion of the total non-empty region area. The table updates during the layout process.

Table rows are one of three cases:

• Black: Desired, present regions.
• Orange: Desired, missing regions.
• Red: Undesired, present regions.

The total area difference is a measure of diagram quality. The lower the value, the better the diagram matches the area specification. A value of zero means the diagram exactly matches the area specification. Note: This value is built by summing proportion differences but it can be larger than 100 due to counting both missing, desired regions and present, undesired regions.

The stress value is another measure of diagram quality, used previously by the venneuler system. The lower the value the better the diagram matches the area specification. A value of zero means the diagram exactly matches the area specification.
