A stacked bar chart displays the time required for five business processes, comparing required working hours against missing hours for each category. The chart uses d3.v4 to bind data from a local JSON file, structuring the dataset through a map function that generates intermediate array objects for rendering. The visualization relies on D3’s data-join and scale APIs to position and size the bars, with each process split into two stacked segments representing the required and missing hour values. The accompanying HTML file sets up a full-viewport body and loads D3 from the official CDN.
