Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] There are three criteria for evaluating the pros and cons of treemap layout algorithms:
[0034] i. Average aspect ratio
[0035] The aspect ratio measures the squareness of the rectangle, defined as max{length / width, width / length}, the aspect ratio is always greater than or equal to 1, the closer it is to 1, the closer the rectangle is to a square. The average aspect ratio is defined as the average of the sum of the aspect ratios of all rectangles in the visualization.
[0036] ii. Sequence
[0037] Sequentiality is the positional sequence of the data elements themselves in the original ...
