Live Brexit tweets sentiment analysis
November, 2018
Tech stack: Twitter Firehose API, D3.js, SVG, Java and Omniscope
This was a one-day project for the Big Data London exhibition. The visualisation shows recent tweets about Brexit from the last 5 minutes automatically updated falling in real time based on a vertical time axis and horizontal sentiment axis. The overall distribution is then accumulated at the bottom of the chart.
Every tweet is represented as a ball sized by the number followers of the account, coloured and positioned from left to right based on the sentiment.
Tweets are extracted and processed using Omniscope from a Twitter Firehose and the topic and sentiment score analysed from the text.
