title: How to do a semi circle donut with highcharter library?
body: <p>I'm trying to do a semi circle donut with highcharter library but I only know how to do a pie chart. I know that with JS you can do it by adding "startAngle" and "endAngle" but I want to know how to do it with R:</p>
  
  <pre><code>A &lt;- c("a", "b", "c", "d")
  B &lt;- c(4, 6, 9, 2)
  
  C &lt;- c(23, 26, 13, 15)
  df &lt;- data.frame(A, B, C)
  
  highchart() %&gt;% 
    hc_chart(type = "pie") %&gt;% 
    hc_add_series_labels_values(labels = df$A, values = df$B)%&gt;%    
  
    hc_tooltip(crosshairs = TRUE, borderWidth = 5, sort = TRUE, shared = TRUE, table = TRUE,
               pointFormat = paste('&lt;b&gt;{point.percentage:.1f}%&lt;/b&gt;')
    ) %&gt;%
  
    hc_title(text = "ABC",
             margin = 20,
             style = list(color = "#144746", useHTML = TRUE))
  </code></pre>
