5 Crafting a data story using the DIKW pyramid
This chapter covers
- A homelessness tale, our scenario for this chapter
- What a data story is and how it relates to the DIKW pyramid
- How to incorporate generative AI into the DIKW pyramid
Creating stories is the most exciting part of data storytelling. It’s really about following a plot with a beginning, a main point, and a conclusion—just like in the stories at the cinema or theater. Here, however, there are constraints imposed by the data. In this chapter, we will focus on using the DIKW pyramid by describing two examples. The first example will analyze the problem of homelessness in Italy, and the second will examine the problem of fake news on a hypothetical website. We will also describe the concept of a data story and how it relates to the DIKW pyramid already discussed in the previous chapters. Finally, we will describe some strategies to incorporate generative AI in the DIKW pyramid, based on how to write specific prompts for ChatGPT to generate the context of a chart and for DALL-E to generate contextual images to incorporate into the chart.
