This visualization presents a multi-series bar chart of personnel hours (JH) by team, task, and degree level, using data from a CSV file with team, degree, task, and JH columns. The view shows three teams (A, B, C) across three tasks (IT, Livraison, RH) and three degree levels (0, 1, 2). The chart encodes each degree value as a scaled circle positioned at the center of its corresponding cell, with radius proportional to the JH value and fill color varying by degree level using a green color scheme. It uses D3.js (v5) to load the CSV, nest data by team and task, and render the SVG with band scales for both x and y axes.
