This post explains how to build a simple circle packing chart with Python. It uses the circlify library to compute the circle positions, and matplotlib for the rendering. It considers a dataset with only 1 level of hierarchy.

The circlify package is a pure Python implementation of a circle packing layout algorithm. It has been developped by Jerome Lecomte and lives on github. 🙏🙏. You can install it with pip install circlify. Circlify can work without a hierarchical structure, i.e. with just a set of numeric varialbles that will be each displayed as a bubble.

Jan 30, 2021 · A pure Python implementation of the circle packing algorithm detailed in Wang et al. (2006). Visualization of large hierarchical data by circle packing. Proc of the SIGCHI, 517-520. Installation. Using pip: pip install packcircles or directly using setup.py: git clone https://github.com/mhtchan/packcircles.git cd packcircles python setup.py ...

Oct 11, 2016 · You are lucky that there is an existing circle-packing implementation in python (heuristic! ) which is heavily based on modern optimization-theory ( difference of convex-functions + Concave-convex-procedure ).

The function pack takes an iterable of the radii of the circles to pack and returns a generator that yields the layout of each circle as tuples in the form (x_coordinate, y_coordinate, radius).

Jul 10, 2022 · Pure Python implementation of a circle packing layout algorithm, inspired by d3js and squarify. Circles are first arranged with a euristic inspired by the A1.0 of [Huang-2006], then enclosed in a circle created around them using [MSW-1996] algorithm used in [Bostock-2017].

This post explains how to build a circle packing chart with several levels of hierarchy. It uses the circlize library to compute the bubble position, and matplotlib for the rendering.

Jun 3, 2019 · I'm trying to write a program in Python with Shapely that takes in shape files (right now congressional districts) and "packs" them with circles. The end goal is to have the center points and radii of the circles. I'd like to cover the maximum area with the least amount of circles.

Dec 9, 2021 · This library provides a tool for circle packing in python, using the front-chain packing algorithm by Wang et al. and enclosed by a circle computed using the Matoušek-Sharir-Welzl algorithm. The circle pack code is adapted from d3-hierarchy, which comes with the ISC license found in the LICENSE file. Why?
