VIS Map lays out the IEEE VIS 2026 program as colored squares, each about 250 words of a paper, each in a fixed place. Drawing them needs WebGL 2, which this browser isn't providing. It may be turned off, or the computer's graphics may be blocked, as they often are on work machines and virtual machines. A current Chrome, Firefox or Safari on another device should show the map.
Meanwhile the text itself is on IEEE VIS.
