Hi @yoshi6jp ,

Thank you very much for opening this PR, it will be an awesome addition to the library.

From an API point of view, what do you think about making it like the node.viewGenerator?

Which would be :

• renaming pathGenerator to viewGenerator
• passing all the node props to the generator instead of passing lineProps and other props, once more to make the API look like the nodeGenerator API

Hi @dgautsch , @antoninklopp
I fixed PR

• rename pathGenerator to viewGenerator
• change link.viewGenerator parameters

viewGenerator: (props, options) => (
    <CustomLink
     label={props.label}
     source={props.source}
     target={props.target}
     id={options.id}
     textProps={options.textProps}
     lineProps={options.lineProps}
  />)
