title: How to plot a set of points on the ground in Unity3D?
body: <p>I have to plot a set of points on the ground on my Unity3D project. The 2D plot of the points looks similar to this: 
  <img src="https://i.imgur.com/Oa3nuCT.jpg" alt="Plot">[1].</p>
  
  <p>The brute-force method would be to assign gameObjects to each points but since there are thousands of points it will be costly. I am looking for some possible usage of Unity Particle System to achieve my goal. In fact any possible methods would be fine. </p>
  
  <p>My final goal is to highlight those points on the ground to indicate the path for my Player to follow. </p>
  
  <p>Any suggestion would be appreciated.</p>
