## Set a Domain and a Range on a Scale
|
|
|
|
### Hint 1
|
|
|
|
Use the `.domain()` and `.range()` functions.
|
|
|
|
### Hint 2
|
|
|
|
Both the the `.domain()` and `.range()` functions accept an array of two elements.
|
|
|
|
## Spoiler Alert | Solution Ahead
|
|
### Solution
|
|
|
|
The `domain` and `range` functions can be chained, and the following is the solution:
|
|
|
|
```javascript
|
|
<body>
|
|
<script>
|
|
const scale = d3.scaleLinear()
|
|
.domain([250, 500])
|
|
.range([10, 150]);
|
|
const output = scale(50);
|
|
d3.select("body")
|
|
.append("h2")
|
|
.text(output);
|
|
</script>
|
|
</body>
|
|
```
