This scatter plot displays investment-grade corporate bond values over time, with each point representing a daily observation. The chart uses a linear time scale on the x-axis for dates and a linear scale on the y-axis for bond values, with all points rendered as steelblue circles. The visualization is built with D3 v5, utilizing `scaleLinear`, `axisBottom`, and `axisLeft` from the D3 API to construct the axes, while the data is loaded from a CSV file and rendered as SVG circles.
