Demo

The extension fetches the analysis report from the RESTful API and renders the JSON file to the popup window. The image at the center is showing a WordCloud that contains words that are mostly mentioned in comments. At the bottom, there are emotional analysis generated by Google NLP API, and tags of the video.
