Covid Vaccines

This project is hosted by this Observable notebook (text in Italian). In the early days of the COVID-19 vaccination in Italy, the official symbol of the vaccination plan was a primrose. Borrowing that flower, I created a D3-based library called the Flower Plot, a dataviz that lies somewhere between stacked normalized charts and pie/donut charts. Indeed, each petal represents a data category, like slices for pie charts or bars in bar charts. The extension of each petal (i.e., start / stop angles) represents a proportion of the whole.

In this project, I exploited a collection of flower plots to describe the dynamics of the vaccination plan in Italy per region. Petals describe eligibles for the vaccines, broken down by age. Moreover, petals gradually color as people get vaccinated.
