title: How to draw routes in tableau with line thickness indicating the cost incurred for that route?
body: <p>I have transport/logistics data which I am trying to visualize using mapping capability of Tableau. I have data at route level i.e origin &amp; destination combinations defined as city, country level for Europe &amp; UK.I have information about cost &amp; volume flow across different origin and destination points.</p>
  
  <p>I know we can draw straight lines from one point to another if we have the lat-long data for each point. Referring to the link below

  <p>I have three questions:
  1. Is there an easy way to get the zip codes and latitude-longitude data along with distance between all points in my data? I know SAS directory has the data for US zip codes but I am working for Europe &amp; UK locations</p>
  
  <ol>
  <li><p>How to change color or thickness of lines based on the cost incurred or volume transported on a particular route?</p></li>
  <li><p>Can I draw actual road distance between two points? I mean not the straight displacement line but the route similar to how Google Map shows.</p></li>
  </ol>
  
  <p>Please share your knowledge nuggets or experience around this.</p>
  
  <p>Thanks,
  Nisha</p>
