This line chart visualizes the annual sales figures of KinderJoy, highlighting trends in sales performance over time. The visualization uses D3.js v5, employing scales such as `scaleTime` for the x-axis (Year) and `scaleLinear` for the y-axis (Sales in Thousands), with a basis-spline curve smoothing the data line. SVG elements render the axes and path, while the data is loaded from a CSV file. The chart emphasizes clarity with labeled axes, gridlines, and a clean, minimalist design, making it easy to observe yearly fluctuations in sales.
