Records with missing values should be clearly shown in the scatterplot
|Assignee:||Krithika Manohar||% Done:|
The records with missing X data could be displayed to the left or right of the axis range, and the records with missing Y data can be displayed above or below the axis range. Records with both missing X and Y data can be displayed in the upper-right or lower-left corner, outside the axis range.
The records with missing coordinates should probably be stored in separate KD-trees, since they can't be queried the same way as the other data.
