⚡ Data scientist, I enjoy telling stories with data. I'm currently learning D3.js and working on hobby projects, Mapbox visualizations, and fiddling with Juniper network data.

Purpose-built for displays of data
Observable is your go-to platform for exploring data and creating expressive data visualizations. Use reactive JavaScript notebooks for prototyping and a collaborative canvas for visual data exploration and dashboard creation.
