SVG | Max Graze | Observable"}] 34:T57b,md ` ### Step 2: Make your animation In a new cell, start your animation and select the elements you want to move. There are a few different methods to select. Either by using \`querySelector\` to select elements from within your chart's cell, or you can use it directly in your GSAP animation. **Do not use \`d3.select\`**. \`\`\`js let demo = svg.querySelectorAll('.demo') \`\`\` or \`\`\`js gsap.to('.demo', ..... ); \`\`\` The following don't work: \`\`\`js let demo = d3.select(svg).selectAll('.demo') let demo = d3.selectAll('.demo') \`\`\` you'd need to use: \`\`\`js d3.selectAll('.demo')._groups[0] \`\`\` (Thanks Mario!) We have to set our boxes to have an opacity of 0, so they don't show up right away. \`\`\`js gsap.set(demo, {opacity: 0}) \`\`\` Check the console to see what these select. Then we create our little stagger animation. Since we are using buttons to prototype it, I've added \`paused\` so that it doesn't play right away. I've used \`gsap.to\` and so I write the state that I want the animation to go to. \`\`\`js const anim = gsap.to(demo, { paused: true, opacity: 1, stagger: 0.5 }); \`\`\` ### Gotchas: Be careful with prototyping your tween in the reactive notebooks. If you apply a style change and then want to get rid of it, you might have to refresh the page to see your tween revert to how it was before. If all else fails, reload the notebook. `35:[] 32:{"id":"7c46b4142b8fbc13","slug":"variations-on-waffle-charts-ft-svg","title":"Variations on a waffle chart ft.
