title: Creating a Network Graph using igraph in R
body: <p>I need some help getting started using igraph in R. I have a .csv file with three columns: </p>
  
  <ol>
  <li>the first column is a String that represents the "from" node, </li>
  <li>the second column is a String that represents the "to" node, and then </li>
  <li>the third column is a Double that represents the strength of the relationship.</li>
  </ol>
  
  <p>I have the file read into R, and I tried turning it into a dataframe and graphing it that way, but it didn't work. 
  My final goal is to turn this .csv file into a weighted network graph, but I'm not sure how to start.</p>
