 IEEE VIS 2025 will be the year’s premier forum for advances in theory, methods, and applications of visualization and visual analytics. The conference will convene an international community of researchers and practitioners from universities, government, and industry to exchange recent findings on the design and use of visualization tools.
 
-In 2025, the conference is again moving to the old continent, and we cannot wait to welcome you to the heart of Europe, in the beautiful city of Vienna!. Vienna is a [welcoming host](https://meeting.vienna.info/en/why-vienna/good-reasons-for-vienna) which excels at traditional hospitality, and a highly efficient modern city. It is a major urban center, but still has the largest proportion of green space of any large European city. In addition to the well-known cultural highlights, it’s the capital’s outstanding infrastructure that sets Vienna apart as a remarkably clean and safe city. The public transportation network and short walking distances between attractions mean that it takes no time at all to get around, with some of Europe’s most beautiful sights and the finest culinary delicacies around every corner. Sustainability is a key factor - from renewable energy forms and the outstanding drinking water fresh from the city’s taps. Like many other events in Vienna, VIS 2025 will be certified as a [green meeting](https://meeting.vienna.info/en/sustainability).
