This bar chart displays average SAT verbal scores across nine years, from 1999 to 2015, using a sequential color scale to encode score magnitude. The data is loaded from a CSV file via `d3.csv` and rendered as SVG rectangles. Bars are sorted by score and colored using `d3.scaleQuantize` with ColorBrewer’s Reds palette, accompanied by a legend from `d3.legendColor`. Interactive features include a yellow tooltip on mouseover, with axes and labels formatted using D3’s standard scale and axis APIs.
