This visualization shows the total number of illnesses from national disease outbreaks, aggregated by month and colored by the primary transmission mode. The bar chart, built with Vega-Lite and rendered through the vega-lite-api, uses d3.csv to load the outbreak dataset from a GitHub gist. Each bar represents a month, with height proportional to the summed illness count, while color distinguishes transmission categories such as foodborne or person-to-person. The view automatically fits the full browser window, with customized axis styling and tooltips for interactivity.
