Showcase Plot doesn't have link to the code

[bigbug]

The example page at http://uber.github.io/react-vis/examples/showcases/plots doesn't show a link to the implementation. Since this is the only chart with legends enabled, this is kinda bad.

Solution: add a link to https://github.com/uber/react-vis/blob/master/packages/showcase/plot/complex-chart.js at

react-vis/packages/showcase/showcase-sections/plots-showcase.js

Line 256 in 2ac4544

<section>

The code would probably look like this:

<a {...linkProps} href={exampleLink}>
  {' '}
  View Code
</a>
