First Viz Iteration: Streamgraph

After this week's reading and lecture, I decided to change my stacked bar chart to a streamgraph for this iteration. Streamgraphs are often used to show changes in different categories over time when there are many categories and when they start and stop at different times. I decided to use this graph because the purpose of this visualization is to show the trend and patterns of changes in the medium used in artworks over time. I think this graph type shows the trend better as it gives a nice flow of each category/medium.
