Second day of Dashboard Week, and today was all about accessibility, with my task being to create a dashboard based on UK Covid data, accessible to as many people as possible. The data included case detections, hospital admissions and deaths, all grouped by date and region.
I decided to look primarily at mortality rate (cheery!), and how that changed over the two year period, by looking at hospital admissions, new cases, and deaths. I built the charts and dashboard from the start with accessibility in mind - the charts were simple, just one line on each of the three, and the text was clear, bold and easy to read. The main findings of the dashboard were all written in text boxes as well so that people using screen reading software would have no problems with them.
I was also keen to make sure the dashboard could be viewed on as many devices as possible, since some people use tablets or smaller-screened devices rather than computers. I used Tableau's option of manually designing a phone layout to make sure this would be fine, which involved splitting up one of the text boxes to make sure all the information stayed with the appropriate charts.
Finally, since there was time, there were bar charts as well, comparing rates across regions and nations, compared to the UK average. Again, these were presented simply and with text in bold, to make everything as accessible as possible.
