what is x4-analysis fr?

This is a fan-made tool for players of the space trading game X4: Foundations. It reads your saved game file and turns it into a dark themed, tabbed dashboard you can open in your web browser, showing an interactive map of your in-game empire along with trade and market data. It is a Python rewrite and major expansion of an earlier tool built in the R programming language by another fan. Where that older version needed a huge amount of memory and several minutes to process a save, this one reads a large savegame in a single pass in just seconds. Getting started does not require installing Python at all. You can download a ready-to-run version for Windows or Linux from the project's releases page, or use a tool called uv to run it with one command. Once run, it automatically finds your most recent savegame, analyzes it, and opens a dashboard file in your browser. The dashboard works fully offline once generated, with no need for an internet connection. The dashboard has several tabs. A map tab shows an interactive view of the galaxy you can pan and zoom around, with details on stations, resources, and which faction controls each area. Trade tabs break down your empire's income and spending over time, by trading partner and by item. A market tab looks at supply and demand across the entire game universe, helping you spot where prices are unusually high or low so you can profit from the gap. Other tabs cover your fleet of ships and the wider universe's stations and factions. The tool includes reference data for the current version of the game and its official add-ons built in, so nothing extra needs to be downloaded for a standard installation. It can also pull in data for modded ships if asked to. Modded saves are supported and unrecognized ships or factions are handled gracefully rather than causing errors.
