# Visualizing California Water Quality With Python

# Source Data
[California Open Data Portal](https://data.ca.gov/) provides water quality data available [here](https://data.ca.gov/dataset/water-quality-data). This contains data ranging from 1968 to 2022 and has results for parameters such as dissolved oxygen and chemical levels. In this example, I will be looking at the Dissolved Oxygen Levels in California.

# Figure 

The graphic below shows the monthly Dissolved Oxygen Level for each station. The stations within each county will share the same shape but have a different color.

Notes
- Hovering over a point will show additional information for the point
- Clicking on a station in the legend will highlight points from that station
- Viewing in landscape mode on mobile devices is advised
