Contributions summary:Alexis's commits primarily focused on enhancing the user interface of the sigma.js library by implementing changes to improve scaling within the graph visualization tool. This involved modifying the core graph rendering functions, specifically `Graph.rescale()`, to ensure that node sizes and margins are accurately considered during the scaling process. They also fixed some minor UI-related problems, like the position of the label background and handling the new edge type, thus contributing to the usability and visual accuracy of the library.
