D3 Test Fork
This visualization plots student grades against video views in a 2013 HarvardX/MITx course dataset. The scatterplot uses a log scale for the x-axis to accommodate data spread, with D3 v5’s `scaleLog` and `scaleLinear`. Built with React and rendered as SVG, the code defines custom `AxisBottom`, `AxisLeft`, and `Marks` components. Dots are initially colored a fixed red, though the author notes an intention to color by institution, as seen in the `colorValue` variable and `schemeCategory10` import.
