title: Javascript Canvas Lat Lng Plotting
body: <p>I want to create a data visualization similar to this:</p>
  
  <p><img src="https://i.stack.imgur.com/UnCHh.png" alt="enter image description here"></p>
  
  <p>...but for the entire globe. The canvas size will be arbitrary but won't need to resize with the browser (I will set the width and height before I start plotting points). I need to figure out a way of converting latitude and longitude coordinates to points on the canvas. Does anyone know how to do it?</p>
