title: How do I assign different dots different colors in a scatter plot made with MatPlotLib?
body: <p>Using MatPlotLib and Python, I am making a scatter plot of laptops that has cost on the x-axis and rating on the y-axis. The data is now stored in a tab-separated file.</p>
  
  <p>This link describes MatPlotLib scatter plots.

  <p>Each laptop's brand is Lenova, HP, or Dell. I want to assign different colors for dots representing laptops of each brand. For instance, Dell laptops are marked by a blue point, while Lenova laptops are represented by a red point.</p>
  
  <p>How can I do that?</p>
