This interactive bar chart visualizes one week of "gunz" and "roses" values per day, with bars animated via draggable handles. Users click and drag the handles to modify data values, which dynamically updates bar heights and text labels. The visualization uses D3 v5 with SVG elements, including `scaleBand`, `scaleLinear`, `drag()`, and `mouse()`, and includes a color legend with `scaleOrdinal`. Data is loaded from a local JSON file, and the chart updates its y-axis limits as users interact.
