Line Chart with Interpolation
-----------------------------
This chart shows a line chart with the path interpolated. A full list of interpolation methods is available `in the documentation <https://altair-viz.github.io/user_guide/generated/core/altair.LineConfig.html?highlight=interpolate#altair-lineconfig>`_.

    import altair as alt
    from altair.datasets import data

    source = data.stocks()

    alt.Chart(source).mark_line(interpolate="monotone").encode(
        x="date:T",
        y="price:Q",
        color="symbol:N"
    )
    # No channel encoding options are specified in this chart
    # so the code is the same as for the method-based syntax.
