This line chart tracks the daily number of motor vehicle collisions in New York City from July 2016 through January 2017, revealing fluctuations that dip on holidays and spike on certain weekdays. The visualization is built as a React component that loads CSV data and passes it to a D3 rendering function, which uses `scaleTime`, `scaleLinear`, `line`, `axisBottom`, and `axisLeft` to draw the plot with labeled axes.
