Building Blocks of Success: Evolution of top 10 LEGO Themes

I wanted to focus on one question and create an interactive visualization. After some data exploration, I found it interesting to see the evolution of the different lego themes over time. There were 152 themes in total, so I decided to focus only on the top 10 (based on the total number of lego sets released). In addition, I wanted to explore a new data visualization & storytelling tool, Flourish. After first cleaning and summarizing data in Excel, I then imported the dataset into Flourish and built the interactive visual which you can find here.
