This animated bar chart compares daily values for "gunz" and "roses" over one week, using grouped bars that users can drag vertically to modify data points. D3.js v5 with SVG renders the visualization, employing `scaleBand` for positioning, `scaleLinear` for the y-axis, and a drag behavior to update bar heights interactively. Hovering a bar displays divergence values relative to the highlighted bar, with a dashed reference line. Data comes from the included `GunzNRosesData.json` file, and the color legend customizes the categorical color scale.
