{{#category_index:D|dot chart}} A chart used to hand-compute the theoretical gravity (or other potential) effect of a 2-D mass distribution; see Figure D-22. The number of dots within the mass outline when a chart is superimposed on a scaled cross-section of the mass multiplied by the anomalous density is proportional to the gravity effect at the chart origin. Also called graticule.
