Data Analyzer

<p>This tool performs data analysis and visualization by generating KNIME compatible Python scripts that operate on an input table to answer a natural language question. The tool interprets the processing prompt and produces Python code that performs the required filtering, aggregation, and analytical operations. It can optionally create a visualization of the results using matplotlib or plotly. The generated script is ready to run inside a KNIME Python Script node and operates directly on the provided input table.</p>
