chart_spec = py`# start with a fake dependency on the libraries being installed:
# ${deps_installed}
# now the basic altair example:
import altair as alt
import json
from vega_datasets import data
cars = data.cars.url
chart = alt.Chart(cars).mark_point().encode(
x=alt.X('Horsepower:Q', scale=alt.Scale(domain=[0, ${max_horsepower}])),
y='Miles_per_Gallon:Q',
color='Origin:N',
).interactive()
# this outputs Map, not Object:
# chart.to_dict()
# which, we could probably correct for directly
# for now, we'll take the hit of encoding and recoding it to JSON:
json.dumps(chart.to_dict())`
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.
