This bar chart visualizes shopping methods by gender, displaying the percentage of males and females who shop Online, In-store, and Mobile. The chart uses stacked bars with different colors for each gender category, alongside a legend and labeled axes. Built with React and D3.js v6, it relies on `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the percentage y-axis, and `d3.axisBottom` and `d3.axisLeft` for ticks. The data is hardcoded as an array of objects, rendered as SVG elements within a 600x400 viewport.
