Method and system for generating data-efficient 2d plots

A computer system comprising:

• a visualization preprocessing system configured to receive data for rendering as a plurality of objects in a chart, the visualization preprocessing system including:
• a virtual display;
• a Z-order optimizer configured to sort the objects into a first order, and configured to swap a pair of objects included in the first order of sorted objects to create a second order of the plurality of objects;
• and
• an optimizer rendering system configured to render the objects in a first graph in the virtual display based on the first order, render the objects in a second graph in the virtual display based on the second order, and determine that a number of visible objects in the first graph is less than a number of visible objects in the second graph;
• and
• a rendering system configured to receive the plurality of objects in the second order from the visualization preprocessing system, and configured to output the plurality of objects for rendering on a display device in an order specified by the second order based on determining that a number of visible objects in the first graph is less than a number of visible objects in the second graph.

A method comprising:

• receiving, by a computing system, data for rendering as a plurality of objects in a chart;
• rendering, by the computing system, the plurality of objects in a first order in a first graph in a virtual display;
• swapping a first object and a second object in the first order of the plurality of objects creating a second order of the plurality of objects;
• rendering the objects in a second graph in the virtual display based on the second order;
• determining that a number of visible objects in the first graph is less than a number of visible objects in the second graph;
• and
• outputting the second order of the plurality of objects for rendering on a display device based on determining that a number of visible objects in the first graph is less than a number of visible objects in the second graph.
