This line chart displays the number of cyber attacks per year from the CISSM dataset. The visualization uses a simple black line against a light gray plot area, with labeled axes for year and attack count. Built with D3.js, the chart employs `scaleBand` for the x-axis and `scaleLinear` for the y-axis to position data points, which are connected using the `line` generator. The code also integrates the `corey-responsive-axis` library for axis labels and utilizes a reactive layout for resizing.
