Vizualisations of Political Hate Speech on Twitter

Recently there's been some media interest in our work on abuse toward politicians. We performed an analysis of abusive replies on Twitter sent to MPs and candidates in the months leading up to the 2015 and 2017 UK elections, disaggregated by gender, political party, year, and geographical area, amongst other things. We've posted about this previously, and there's also a more technical publication here. In this post, we wanted to highlight our interactive visualizations of the data, which were created by Mark Greenwood. The thumbnails below give a flavour of them, but click through to access the interactive versions.

Abusive Replies

Sunburst diagrams showing the raw number of abusive replies sent to MPs before the 2015 and 2017 elections. Rather than showing all candidates, these only show the MPs who were elected (i.e. the successful candidates). These nicely show the proportion of abusive replies sent to each party/gender combination but don't give any feeling per MP the proportion of replies which were abusive. Interactive version here!

Increase in Abuse

An overlapping bar chart showing how the percentage of abuse received per party/gender by MPs has increased between 2015 and 2017. For each party/gender two bars are drawn. The height of the bar in the party colour represents the percentage of replies which were abusive in 2017. The height of the grey bar (drawn at the back) is the percentage of replies which were abusive in 2015 and the width shows the change in volume of abusive replies (i.e. the width is calculated by dividing the 2015 raw abusive reply count by that from 2017 to give a percentage which is then used to scale the width of the bar). So height shows change in proportion, width shows increase in volume. There is also a simple version of this graph which only shows the change in proportion (i.e. the widths of the two bars are the same). Original version here.

Geographical Distribution of Abuse

A map showing the geographical distribution of abusive replies. The map of the UK is divided into the NUTS 1 regions, and each region is coloured based on the percentage of abusive replies sent to MPs who represent that region. Data from both 2015 and 2017 can be displayed to see how the distribution of abuse has changed. Interactive version here!
