This project is an interactive web visualization that helps users better interpret probabilistic snowfall forecasts. Viewers can input their own predicted probabilities by visiting a website like [this one] to find a bar chart of the likelihood of various levels of snowfall in their area. The interface will then convert this information into two visualization formats:
- Quantile Dot Plot
- Original Bar Chart
The quantile dot plot represents the data as hypothetical discrete storms, making snowfall predictions easier to understand. Each dot--or snowflake, in our case--reflects one of 20 possible storms. More details are available in the Process Book.
