This visualization displays a bar chart of the Morley speed-of-light experiment data, with experiment run numbers on the x-axis and speed measurements on the y-axis. The page includes Google sign-in functionality and a Bootstrap-styled navigation bar. Built with React, it uses D3 v5 APIs including `d3.csv`, `d3.tsv`, `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft` to fetch data from a remote CSV and render the chart within an SVG.
