The `d3.scaleSequential` function is a part of the d3 library and is used to create a sequential scale. A sequential scale is a mapping between a continuous input domain and a continuous output range.
Here's an example of how you can use `d3.scaleSequential`:
```javascript
const colorScale = d3.scaleSequential()
.domain([0, 10])
.interpolator(d3.interpolateBlues);
console.log(colorScale(5)); // returns a color value based on the input value
```
In this example, `colorScale` is a sequential scale that maps values between 0 and 10 to colors using the `d3.interpolateBlues` interpolator. You can pass any value within the domain to the scale to get the corresponding color value.
Make sure you have the d3 library properly imported and check if you have the correct version of d3 installed to use the `d3.scaleSequential` function.
