How does circle packing work?
Circular packing or circular treemap allows to visualize a hierarchic organization. It is an equivalent of a treemap or a dendrogram, where each node of the tree is represented as a circle and its sub-nodes are represented as circles inside of it.
What is circle packing problem?
Circle packing in a circle is a two-dimensional packing problem with the objective of packing unit circles into the smallest possible larger circle.
How do you pack circles?
A circle packing is an arrangement of circles inside a given boundary such that no two overlap and some (or all) of them are mutually tangent. The generalization to spheres is called a sphere packing….Circle Packing.

What is packing in mathematics?
packing, in mathematics, a type of problem in combinatorial geometry that involves placement of figures of a given size or shape within another given figure—with greatest economy or subject to some other restriction.
Which type of data does a circle pack best represent?
Circle packing is great for showing distribution and part-to-whole relationships in large data sets. You can show an overview of the groups and relationships in the data. You might use color to shade the circles to add another variable to your visualization.
What is the packing density of a circle?
circle packing in the plane. The density of this circle configuration is. π √ 12 ≈ 0.906 90. In geometry, circle packing refers to the study of the arrangement of unit.
How many diameters can fit in a circle?
infinite
Every circle has an infinite number of possible diameters. The formula for finding the diameter of a circle is two times the radius (2 * radius).
What is a packing pattern?
1. Solves the pattern selection problem for constructing pattern database search heuristics. One bin represents a container for the abstract state space and approximates the memory usage for pattern database construction. Multiple bins apply for disjoint pattern database construction.
What is sunburst diagram?
A Sunburst Diagram is used to visualize hierarchical data, depicted by concentric circles. The circle in the centre represents the root node, with the hierarchy moving outward from the center.
What is a sunburst chart?
Sunburst chart, known by multiple names such as ring chart and radial treemap, is used to visualize a hierarchical dataset. It shows hierarchy through a series of concentric rings, where each ring corresponds to a level in the hierarchy. Each ring is segmented proportionally to represent its constituent details.
What is meant by packing density?
Packing density (α) is the ratio of the volume of the fibers to the volume of the fibrous media. In aerosol filtration, the fibrous media largely present packing density values lower than 20–30%.
What is circle packing in geometry?
A circle packing is an arrangement of circles inside a given boundary such that no two overlap and some (or all) of them are mutually tangent. The generalization to spheres is called a sphere packing. Tessellations of regular polygons correspond to particular circle packings (Williams 1979, pp. 35-41).
How do you find the radii of a circle packing?
Using discrete conformal mapping, the radii of the circles in the above packing inside a unit circle can be determined as roots of the polynomial equations The following table gives the packing densities for the circle packings corresponding to the regular and semiregular plane tessellations (Williams 1979, p. 49).
What is a sphere packing?
The generalization to spheres is called a sphere packing. Tessellations of regular polygons correspond to particular circle packings (Williams 1979, pp. 35-41).
