Basic Code Solution:
<body>
<script>
const dataset = [12, 31, 22, 17, 25, 18, 29, 14, 9];
d3.select("body").selectAll("h2")
.data(dataset)
.enter()
.append("h2")
.text((d) => (d + " USD"))
.style('font-family', 'verdana')
</script>
</body>
Code Explanation:
- the
style
method takes 2 arguments, the first is the key and the second the value - key in the
style
method is the property name that you would use in a CSS declaration - value is used just as a value would be used in a CSS declaration
- Since we are in JavaScript and
style
is a method we are calling, quotes must be used for the arguments. Otherwise, the function would try to use the value of the variablesfont-family
andverdana
, which do not exist and would each throw a ReferenceError
