Hi. I'm Nicolas Lambert, research engineer in geographic information science at CNRS (France). My job is to draw maps and teach cartography at the university. I am a geographer 🌎, and not really a developer 🖥️

We can do the same map by using colors on contours
bertin.draw({
params: {
projection: d3.geoInterruptedMollweideHemispheres(),
clip: true
},
layers: [
{
type: "bubble",
geojson: data,
k: k,
leg_round: 0,
values: "pop",
leg_x: 100,
leg_y: 300,
leg_divisor: 1000000,
leg_title: "Population (million inh.)",
tooltip: ["$name", "$region"],
fill: "none",
strokeWidth: 2.5,
stroke: {
type: "typo",
values: "region",
leg_title: `The
Continents`,
leg_x: 100,
leg_y: 100
}
},
{
type: "layer",
geojson: geom,
fillOpacity: 0.35,
fill: "white",
stroke: "none"
},
{ type: "graticule" },
{ type: "outline" }
]
})
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.
