chore(deps-dev): bump altair from 4.2.2 to 5.1.1

[dependabot]

Bumps altair from 4.2.2 to 5.1.1.

Release notes

Sourced from altair's releases.

Version 5.1.1

What's Changed

• Fix doctest and run doctests in altair module by @​jonmmease in altair-viz/altair#3175
• infer dtype pandas fallback by @​jonmmease in altair-viz/altair#3179

Full Changelog: vega/altair@v5.1.0...v5.1.1

Version 5.1.0

What's Changed

• Update Vega-Lite from version 5.8.0 to version 5.14.1; see Vega-Lite Release Notes.

Enhancements

1. The chart.transformed_data() method was added to extract transformed chart data

For example when having an Altair chart including aggregations:

import altair as alt
from vega_datasets import data
cars = data.cars.url
chart = alt.Chart(cars).mark_bar().encode(
y='Cylinders:O',
x='mean_acc:Q'
).transform_aggregate(
mean_acc='mean(Acceleration)',
groupby=["Cylinders"]
)
chart

Its now possible to call the chart.transformed_data method to extract a pandas DataFrame containing the transformed data.

chart.transformed_data()

This method is dependent on VegaFusion with the embed extras enabled.

2. Introduction of a new data transformer named vegafusion

VegaFusion is an external project that provides efficient Rust implementations of most of Altair's data transformations. Using VegaFusion as Data Transformer it can overcome the Altair MaxRowsError by performing data-intensive aggregations in Python and pruning unused columns from the source dataset.

The data transformer can be enabled as such:

import altair as alt
alt.data_transformers.enable("vegafusion") # default is "default"

DataTransformerRegistry.enable('vegafusion')
