title: Sankey D3.js sankey.link is not a function
body: <p>I'm new to JS/D3.js (so thanks in advance for any support). I'm trying to create a basic sankey diagram using Gerardo's d3.v5 fork  <a href="https://bl.ocks.org/GerardoFurtado/ff2096ed1aa29bb74fa151a39e9c1387" rel="nofollow noreferrer">https://bl.ocks.org/GerardoFurtado/ff2096ed1aa29bb74fa151a39e9c1387</a> however when I try to run the same script I'm getting the error:</p>
  
  <p>"Uncaught TypeError: sankey.link is not a function"</p>
  
  <p>What am I missing? Looking through the latest version of d3-sankey I cannot see the function, is this from a previous version of d3-sankey? Whats the alternative now if that is the case? </p>
