- The isomap incorrectly connects the 22 and 24 isopleths with a single line that passes through a data point labeled "23". Isopleths must not cross, and a data point must lie between its two bounding isopleths. A value of 23 should be located between the 22 and 24 lines, not on a line connecting them.
- The dashed line segment within the red circle is an error because it represents an isopleth that does not follow the rule of connecting points of equal value. It appears to connect points of different values (22 and 24) or is drawn in a way that violates the principle of contouring, where each line must represent a constant value.
