Let Dashboard Week Commence… Day 1: Accessibility

In this blog, I will talk about our challenge for day 1 of dashboard week, as well as some super useful things I learnt about on the way.

Overview of the Brief

Make a pitch to the Department of Health, visualising UK COVID data, whilst ensuring that your analysis is as accessible as possible.

Plan

Considerations included:

·         Off-white background

·         Consistent colour scheme representing the three main metrics that separate ‘spread’ and ‘severity’ of COVID-19

·         Intro- sets colour consistency, context for a range of data fluencies

·         Download cross-tab button- where graphs cannot be narrated

·         Planned containers for smooth tabbing- creating a natural order for screen readers

·         Double encoding with shape and colour

·         Font- veranda because capital i and l aren’t the same letter

·         Font size- minimum 14

·         .Gov showed a good county heat map which I aimed to hyperlink. Maps cannot be seen by screen readers

·         Off-white background for contrast

Outcome

Further considerations considered:

·         Captions- extra description of graphs for screen readers

·         Descriptive titles: for screen reader/ clarity

·         Marking key points- highlight key observations for you

·         Consistent axis e.g. time was always measured as quarter and year

·         Number format rounded for ease of readers/ limit confusion

Dashboard next steps:

·         Universally bigger font size. Some of the default axes need changing

·         Word choice for ratios

·         Keep working at tabbing at keyboard shortcuts

·         Spacing

·         Edit my tooltips

Reflection

Considering how much I learnt in 2 hours, accessibility is an after thought to normal practices, including dashboard design. I will definitely take some of the tips I learnt today, such as descriptive, statement titles and font/ size considerations, to enrich my future dashboards.
