Award-winning creative focused on data-driven art and visualizations, trying to push the boundaries of the web one visual story at a time ✨
Introduction to SVG and D3.js1. Draw a flower petal on the screen2. Select existing petal(s) and bind movie data3. Create a petal for each movie4. Size each petal based on its movie's rating6. Add filter by options7. Position film flowers by the genres they shareWorkshop Utility Functions
5. Turn petals into flowers for each movie
g = svg.selectAll('g')
.data(flowers).enter().append('g')
text = g.append('text')
path = g.selectAll('path')
.data(d => {
return _.times(d.numPetals, i => {
// create a copy of the parent data, and add in calculated rotation
return Object.assign({}, d, {rotate: i * (360 / d.numPetals)})
})
}).enter().append('path')
{
g.attr('transform', (d, i) => `translate(${d.translate})`)

One platform to build and deploy the best data apps
Experiment and prototype by building visualizations in live JavaScript notebooks. Collaborate with your team and decide which concepts to build out.
Use Observable Framework to build data apps locally. Use data loaders to build in any language or library, including Python, SQL, and R.
Seamlessly deploy to Observable. Test before you ship, use automatic deploy-on-commit, and ensure your projects are always up-to-date.
