This visualization shows the number of patients brought dead to a hospital, broken down by age group, with data ranging from 10 patients in the 0-20 age bracket to 120 patients in the 60-80 bracket. It uses a line chart where the x-axis represents age groups and the y-axis represents patient counts. The chart is rendered using D3.js APIs including `scaleLinear` for axes, `axisBottom` and `axisLeft` for tick marks, and `line` for generating the path. Rather than a thin line, the path is drawn with a stroke-width of 20 pixels, creating a thick band that emphasizes the trend across age categories.
