title: Shiny App - Build an interactive help for the user
body: <p>I'm learning (mostly for fun) shiny and i'm building a dashboard with some tabular data and ggplot graphs.</p>
  
  <p>I'd like to know if there's a possibility to implement a sort of interactive help for the app users, i.e the user pass its mouse pointer on a certain graph and it will pop up a brief description of the plot. When the user move the mouse pointer away the brief description should disappear. </p>
  
  <p>I 've just discovered <code>helpText()</code> function but obviously is far away from what I'd like to implement. </p>
  
  <p>I may add that I don't know any JS and I know basics (very basics) of html and css.</p>
  
  <p>Thanks</p>
