Frontend machine coding - Responsive Bar Chart Component Built a responsive, animated Bar Chart component as part of machine coding practice. Key insights: 1. Bar height is calculated using a scale function based on the max value in the dataset. "(value / maxValue) * chartHeight;" 2. Chart component designed using Compound Component Pattern + Context. 3. To animate bars from 0 to target height, use a 2-phase render with requestAnimationFrame so the browser can properly trigger CSS transitions. 4. Use outline instead of border to avoid reflow.
