Dweet the tone and sentiment of a Tweet!

README.md

This flow provides an example of how you can use IBM Watson API for "tone" analysis of text.

1. The flow starts with the Twitter node, in the provided example it is looking for #IBM.

2. The text of the tweet is passed through both the "sentiment" node, and "tone analyser v3" node (an IBM Watson Service).

3. The payload is then formatted to contain the original text, and the results from the tone and sentiment analysis.

4. This payload if then sent to a thing (see https://Dweet.io).

I have have used a "sparkline" in https://Freeboard.io to show the trend...
