Demo not showing anything

[bjersey]

Hi, I set up the demo per the instructions here: https://heroku.github.io/kafka-demo/ but I'm not seeing any data on the app. Can someone help ensure I configured everything properly?

Here's my setup:

• data-ingest:
  • KAFKA_TOPIC=foobar
  • TWITTER_TRACK_TERMS=movies,hadoop,johnwick
• data-fanout:
  • KAFKA_TOPIC=foobar
  • TWITTER_TRACK_TERMS=movies,hadoop,johnwick
• data-aggregate:
  • KAFKA_CONSUMER_TOPIC=foobar
  • created a dyno for each of the track terms, and scaled down the web dyno to 0
• data-relatedwords
  • KAFKA_CONSUMER_TOPIC=foobar
  • created a dyno for each of the track terms, and scaled down the web dyno to 0
• data-visualization:
  • TWITTER_TRACK_TERMS=movies,hadoop,johnwick

I also attached the Kafka cluster to each of the five apps above. However, I'm still seeing empty on the app:
