This interactive timeline visualizes the six steps for hosting a static website on AWS S3, with clickable circles revealing detailed instructions for each step. The visualization uses React for UI state management and D3.js v7 for SVG rendering, including `scalePoint` for horizontal positioning and `selection.join` for data binding. Steps are loaded from a local CSV file, with connecting lines between circles and completion markers indicating progress. The design adapts responsively to container dimensions using a custom `ResizeObserver` hook.
