This visualization tracks the author's rank on HackerRank as they solve JavaScript algorithm problems, displaying rank values on a logarithmic scale against time. The chart uses a step-after line and circular points to show rank progression from November 2020 to February 2021, with hover interactions revealing a vertical reference line and detailed date/rank labels. Built with React and D3 v6, it employs `scaleTime` and `scaleLog` for axes, `curveStepAfter` for the line, and SVG rendering for output.
