D3.tip is not a function
<p>I am trying to add a d3.tip to my d3 infographic. According to the d3.tip documentation, I installed the d3.tip with Bower. When the install finished, my terminal screens shows:</p>

<p>I guess it was installed successfully.</p>

<p>But when I added d3.tip to my codes, the console.log keep showing "Barchart2.html:121 Uncaught TypeError: d3.tip is not a function." </p>

<p>Can somebody tell me how to solve the problem, please?</p>
