### Styling line curves

It is possible to style the type of curve used for lines between items, if the default method does not meet your needs.
Available curve styles include `basis`, `bump`, `linear`, `monotoneX`, `monotoneY`, `natural`, `step`, `stepAfter`,
and `stepBefore`.

In this example, a left-to-right graph uses the `stepBefore` curve style:

```
%%{ init: { 'flowchart': { 'curve': 'stepBefore' } } }%%
graph LR
```

For a full list of available curves, including an explanation of custom curves, refer to
the [Shapes](https://github.com/d3/d3-shape/blob/main/README.md#curves) documentation in the
[d3-shape](https://github.com/d3/d3-shape/) project.
