Here is a script [0] to batch process undercloud/overcloud templates
from t-h-t's roles_data(_undercloud).yaml and build graphs (will be put
under the heat-viz repo root).

Few examples attached:
* from the undercloud/puppet/undercloud-role.yaml rendered template
  (the graph name undercloud_puppet_undercloud-role.html) [1]
* docker/docker-steps.j2, rendered as undercloud/docker/post.yaml
  (the graph name's undercloud_docker_post.html) - starts [2], ends [3]
* the latter, reduced by filters applied for steps1,2,pre,post [4],[5]

  and decorated with a custom palette based on the step types:

  ruby heat-viz.rb \
  -f 'Pre|Post|Deployment\b|Deployment[15]|Deployment_Step[15]' \
  -d 'pre[^p],post,prep,step1,step5,docker' \
  undercloud/docker/post.yaml
