This gallery displays four interactive visualizations of MoMA artwork data, covering artists, nationalities, mediums, and departmental classifications. Each visualization loads in an iframe and can be enlarged by clicking, using D3.js v5 selection methods like `selectAll` and classed toggling. The code relies on `d3.select`, `d3.selectAll`, and event handling to toggle full-screen viewing, resizing iframes dynamically. The visualizations themselves are embedded from VizHub, with the surrounding page styling handled by CSS for layout and captions.
