CONCLUSIONS
Including data labels can enhance your data visualizations and strengthen your narrative. But you need to make sure that you are consistent and apply high contrast to be effective with your presentation. In this article, we introduce the importance of using the correct contrast ratios according to the WCAG and standardizing your font style. However, it is also important to incorporate your own creativity into your data visualization. Some rules should be broken in order to improv the narrative. So, be adventurous!
