30DayChartChallenge 2022

Hi, this was my first try at learning about data visualization, aside from a few matplotlib and Seaborn (Python) and d3.js (JavaScript) graphs I'd made earlier. Encouraged and inspired by the #30DayChartChallenge Twitter community, I experimented, had fun, and gained skills in finding data sources, differentiating the various kinds of charts, using pandas and numpy to work with the data, and writing matplotlib code. A couple of the projects also use scipy, plotly, seaborn, holoviews bokeh, streamlit, or R.
