Changes

This PR updates the experiments documentation to include information about the new Traffic preview feature added in PostHog/posthog#47606.

What was added

Added a paragraph to the "Experiment variants" section in contents/docs/experiments/creating-an-experiment.mdx that explains:

  • The visual bar chart showing traffic distribution across variants
  • Color-coded sections for each variant (labeled A, B, C, etc.)
  • The hatched pattern showing users excluded from the experiment
  • How variant splits and rollout percentage interact (with a concrete example)

Why

The traffic preview helps users understand how their rollout percentage and variant splits combine to determine actual traffic distribution. For example, a 50% rollout with a 50/50 variant split means each variant receives 25% of total traffic.

This visual feedback was added to reduce confusion about the relationship between these two settings.
