Covid-19 preventative measures communicated and when. The bar chart depicts the number of measures communicated per tweet. The pie chart shows the distribution of measures when communicated singularly. The chord diagram shows how preventative measures were combined. The steam graph shows which measures were communicated and when: set on a central axis, the a-axis shows time and the vertical area represents the number of tweets. Each colour represents a different preventive measure
