title: Labelling Points on a highcharter scatter chart
body: <p>I want to label each individual point in a highcharter scatter plot. The below code produces a highcharter chart:</p>
  
  <pre><code>library(highcharter)
  df = data.frame(name = c("tom", "dick", "harry"), 
             height = c(170L,180L, 185L), 
             weight = c(65L, 68L, 75L))
  
  highchart() %&gt;%
  hc_add_series(df, type = "scatter", hcaes(x = weight, y = height), showInLegend = FALSE) %&gt;%
  hc_tooltip(pointFormat = "height: {point.y} &lt;br&gt; weight: {point.x}")
  </code></pre>
  
  <p>Hovering over each point shows: "series 1, height: 170, weight: 65" etc.
  I want the labels to show "tom, height: 170, weight: 65" when hovering over tom and similarly for dick and harry.</p>
  
  <p>Thanks</p>
