Help in creating a Graph Illustration

Hello p5js community!

I’m trying to use p5js to build a network map and was wondering whether it is possible to build something like this?


What I’ve in mind is using an object instance to represent each ball. And store the object instances into an array to display them.

I’ve coded something out here:

let storeParticles = []; //Array to store particle instances
let particleSize = 70;

// Stores all the companies' data as an array of arrays.
let companies = [
  ["Brand A", "Consumer", "Country A", "#D40A24"],
  ["Brand B", "Consumer", "Country B", "#00509B"],
  ["Brand C", "Consumer", "Country C", "#452976"],
  ["Brand D", "Health", "Country C", "#0268AA"],
  ["Brand E", "Technology", "City C", "#FFE17E"],

class Particle {
  constructor(name, genre, hq, color, pos) {
    this.pos = pos;
    this.speedX = random(-1, 2);
    this.speedY = random(-1, 2); = name;
    this.genre = genre;
    this.hq = hq;
    this.color = color;

  //Move the particles
  move() {
    if (this.pos.x >= 0 || this.pos.x < width) {
      this.pos.x += this.speedX;
      this.pos.y += this.speedY;

  //Show the particles
  display() {
    ellipse(this.pos.x, this.pos.y, particleSize, particleSize);

  // What happens when balls hit edge
  reachEdge() {
    if (this.pos.x > width || this.pos.x < 0) {
      this.speedX = this.speedX * -1; // reverses direction

    if (this.pos.y > height || this.pos.y < 0) {
      this.speedY = this.speedY * -1; // reverses direction

  // Show company data when mouse is over ball
  hover(px, py) {
    let distance = dist(px, py, this.pos.x, this.pos.y); // calculates the distance between the mouse position and ball position
    if (distance < particleSize) {
      //i.e. mouse position is inside ball
      text(, this.pos.x, this.pos.y);
      text("Genre: " + this.genre, this.pos.x, this.pos.y + 20);
      text("HQ: " + this.hq, this.pos.x, this.pos.y + 40);

function setup() {
  createCanvas(400, 400);

  // For loop to create particle instances and store it in another array
  for (i = 0; i < companies.length; i++) {
      new Particle(
        companies[i][0], //accessing company data from companies array
        createVector(random(width), random(height)) //starts at a random position


function draw() {
  //loop through the storeParticles array and call all methods in class
  for (c = 0; c < storeParticles.length; c++) {


//I'm using a mouseMoved() method here because there isn't a mouseOver() method that allows me to only call a function when mouse hovers over the circle. When mouse is moved, the system checks whether the distance between the mouse position and the centre of every circle via the hover method in the Particle class. If the distance is less than the particle size, that means the the mouse is actually within a circle, triggering the display of the text.
function mouseMoved() {
  for (c = 0; c < storeParticles.length; c++) {
    storeParticles[c].hover(mouseX, mouseY);

What I am having trouble now is figuring out whether is there a way to spread the bubbles out in a pretty fashion like in the picture. For mine, the bubbles are very random and floats around. Could anyone point me to some library I can use? Or any another solutions I could work around to achieve this? If its not possible in p5js, I’m also open to other possibilities too (I can code in Python & Javascript) :slight_smile:

Thank you!

Hello @clermagic224 !
Do you want to make something that looks like a network map or something that is a network map? In other words how important is the accuracy of the placement of the bubbles?

Hi @debxyz

Thanks for the reply! I’m looking into making a network map if that’s possible. But if its not possible, its okay if its something that looks like a network map as well. The accuracy in the placement of the bubbles doesn’t have to be very precise :slight_smile:

traer.physics seems to be a library for that
