This strip chart visualizes the ages of individuals from a police shootings dataset, using a one-dimensional scatter plot with random horizontal jitter to reveal the distribution of ages along the vertical axis. The visualization is implemented in React with D3.js, using `scaleLinear` to map age values to screen coordinates and `extent` to calculate the domain. Data is loaded from a CSV file via the `csv` function in `useData.js`, and the chart is rendered as an SVG with custom React components for the axes and marks.
