This scatterplot visualizes the relationship between mean ELA scores and the proportion of white students in schools, using data from a D3_School.csv file. The chart displays 100 data points as circles, with tooltips showing the mean ELA score on hover. Built with D3 v4, it uses `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and SVG circle elements, with mouseover, mousemove, and mouseleave events controlling tooltip opacity and positioning.
