A clear, insight-first bar chart for visualizing positive vs. negative contributions by day. Each column stacks multiple segments above and below a zero baseline so you can see totals and how each category pushes up or pulls down. Centered axes, mirrored tick labels, and subtle gridlines make comparison effortless across the week. A floating tooltip reveals segment values and the day’s total on hover/tap. Rounded bars and soft gradients keep dense data readable in cards or full-width dashboards. Fully responsive and themeable, it works equally well in dark and light UI and supports smooth load/interaction animations.
