Data Analysis with Chart

L2 Construct: data_analysis_with_chart

Description

Data Analysis With Charts Agent is an AI-powered tool for performing data analysis tasks on tabular data to generate a plotted chart.

It takes a task description and a set of input tables, and returns the processed result table, a plotted chart, and the steps (iterations) taken to achieve the result.

Input:

  • task: A string describing the data analysis task to be performed.
  • tables: A map of table names to Table structures, representing the input data.

Output:

  • success: A boolean indicating whether the operation was successful.
  • iterations: An array of steps taken to achieve the result.
  • result_table: The final processed Table structure after performing the data analysis task.
  • chart_output: A byte array containing the plotted chart in PNG form.

The agent uses to break down complex data analysis tasks into a series of simpler operations, using tools like Join, Filter, GroupBy, Chart, and Finish to manipulate the data and create charts.
