circle-pack

问题 I was writing the code for non overlapping random circles with different radii.I kind of got the deserved, but my 'if' statement that checks overlap or non overlap excludes a number of circles. So, I get lesser number of circles. Here's the code: import pygame import numpy as np pygame.init() display_width = 800 display_height = 500 black = [0, 0, 0] white = [255, 255, 255] red = [255, 0, 0] display_surface = pygame.display.set_mode((display_width, display_height)) clock = pygame.time.Clock()

问题 I'm using https://observablehq.com/@d3/zoomable-circle-packing as an example to try d3 and circle packing in angular. I have the data which seems to be hierarchical and I'm following along the code that's presented. However, my d3.hierarchy() is giving me strange results. For some reason, all d.x , d.y and r are all negative. I couldn't figure out why. I'm still reading some guides and books trying to understand if I can figure out how d3.hierarchy works to understand why the values are

问题 UPDATE: New JSFIDDLE Scaling now working, ditched the defs and rect altogether and just appended the image. But still stuck on translate. The translating is still not working on zoom. I can set the translate to say -100 for both x and y to get the non-zoomed placement correct. But, when zooming, it's of course still translating it -100 and not the larger value it would need to be to keep it in place. Appears to need something in the code in the zoom section toward the bottom. Been messing

问题 This circle pack layout example (http://bl.ocks.org/4063269) is perfect for a project I'm working on, however it sizes all the circles relative to one another: Is there a simple way to specify fixed radii for each circle? I've scoured the source code, examples, google, and stackoverflow and can't seem to find anything helpful. The exact sizing of circles is important to me. 回答1: It is possible, and simple thing to do. The first answer is accurate, but I believe mine is simpler, more explicit,

问题 Here is jsfiddle: This is really good if you have, let's say, 2 political parties, and you want to present election results across several voting units, or similarly structured data. However, I need to visually represents this: (5 political parties instead of 2) (please ignore all raws except "seats"; only "seats" are supposed to be visualized) I would like to have a circle pack inside each force layout node . For example, there should be a balloon called BC containing four smaller circles

问题 Hello All instead of simple Circles, i want to add pie charts in my Pack layout. Lets Suppose this is my pie chart data and pie layout var data=[2,3,4,5] var arc = d3.svg.arc() .outerRadius(50) .innerRadius(0); var pie = d3.layout.pie() .sort(null) .value(function(d) { return d; }); And this is how the packlayout draws the circle var circle = svg.selectAll("circle") .data(nodes1) .enter().append("circle") .attr("class", function(d) { return d.parent ? d.children ? "node" : "node node--leaf" :

问题 I am trying to make a zoomable circle packing chart. I'd like each child circle to contain a smaller chart which would always have the same structure (i.e. 4 columns, only the heights of the bars would change). I have tried adding a simple rect to my chart so far but the rects are not added in the circle and are statics: JS: var margin = 20, diameter = 400; var color = d3.scale.linear() .domain([-1, 5]) .range(["hsl(152,80%,80%)", "hsl(228,30%,40%)"]) .interpolate(d3.interpolateHcl); var pack
