Number input in v5

This is a demonstration of the use of the html 'number' input to rotate a text element using d3.js v5.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 5 of d3.js.

<!DOCTYPE html>
<meta charset="utf-8">
<title>Input (number) test</title>

<p>
  <label for="nValue" 
         style="display: inline-block; width: 240px; text-align: right">
         angle = <span id="nValue-value"></span>
  </label>
  <input type="number" min="0" max="360" step="5" value="0" id="nValue">
</p>

var width = 600;
var height = 300;
 
var holder = d3.select("body")
      .append("svg")
      .attr("width", width)    
      .attr("height", height);

// draw the element
holder.append("text")
  .style("fill", "black")
  .style("font-size", "56px")
  .attr("dy", ".35em")
  .attr("text-anchor", "middle")
  .attr("transform", "translate(300,150) rotate(0)")
  .text("d3noob.org");

// when the input range changes update value 
d3.select("#nValue").on("input", function() {
  update(+this.value);
});

// Initial update value 
update(0);

// adjust the text
function update(nValue) {

// adjust the value
  holder.select("text") 
    .attr("transform", "translate(300,150) rotate("+nValue+")");
}
