"Talk Data to Me - the art of storytelling" by Diana Pholo

Collecting data is now seen as a very important aspect of business. Many companies therefore invest in solutions such as Business Intelligence tools, spreadsheets and dashboards in an attempt to extract useful information from their data. However, these tools still fail to present what is hidden in the data because they do not bring out their underlying significance. This is where data storytelling comes in. It helps to visualise information, understand the narrative behind it and share it.

This talk is aimed at anyone who wishes to get started with storytelling using data. What do you look for? How do you present your findings to stakeholders? Together, we will have a look at common visualisation tools provided Matplotlib, Pandas and Seaborn (accompanied with code snippets and sample outputs). We will then look at the story behind the Harambee youth employment journey data. (Data provided by Harambee Youth Employment Accelerator)
