xinrong-meng opened a new pull request, #48139: URL: https://github.com/apache/spark/pull/48139
### What changes were proposed in this pull request? Support line plot with plotly backend on both Spark Connect and Spark classic. ### Why are the changes needed? While Pandas on Spark supports plotting, PySpark currently lacks this feature. The proposed API will enable users to generate visualizations, such as line plots, by leveraging libraries like Plotly. This will provide users with an intuitive, interactive way to explore and understand large datasets directly from PySpark DataFrames, streamlining the data analysis workflow in distributed environments. See more at [PySpark Plotting API Specification](https://docs.google.com/document/d/1IjOEzC8zcetG86WDvqkereQPj_NGLNW7Bdu910g30Dg/edit?usp=sharing) in progress. Part of https://issues.apache.org/jira/browse/SPARK-49530. ### Does this PR introduce _any_ user-facing change? Yes. ```python >>> data = [("A", 10, 1.5), ("B", 30, 2.5), ("C", 20, 3.5)] >>> columns = ["category", "int_val", "float_val"] >>> sdf = spark.createDataFrame(data, columns) >>> sdf.show() +--------+-------+---------+ |category|int_val|float_val| +--------+-------+---------+ | A| 10| 1.5| | B| 30| 2.5| | C| 20| 3.5| +--------+-------+---------+ >>> f = sdf.plot(kind="line", x="category", y="int_val") >>> f.show() # see below >>> g = sdf.plot.line(x="category", y=["int_val", "float_val"]) >>> g.show() # see below ``` `f.show()`:  `g.show()`:  ### How was this patch tested? Unit tests. ### Was this patch authored or co-authored using generative AI tooling? No. -- This is an automated message from the Apache Git Service.
