This interactive visualization displays the number of H-1B visa petitions by case status across different U.S. states, using a stacked bar chart where each bar represents a state and color segments indicate the case status. The chart is built with the Vega-Lite API, which registers Vega and Vega-Lite in a React environment, and uses d3.csv to load immigration data from the Office of Foreign Labor Certification. The visualization sorts states by petition count in descending order and includes tooltips for detailed values.
