# Support structure for explainability output in the UI:
# Each model should output:
# - Response
# - Helpfulness, Correctness, Coherence, Tone, Bias
# - Reasoning/Explanation why the score was assigned
#
# Radar Chart Inputs Example:
# scores = {
#   'Model': 'GPT-4',
#   'Helpfulness': 0.8,
#   'Correctness': 0.75,
#   'Coherence': 0.85,
#   'Tone': 0.7,
# }

# CSV export format should include:
# model, response, helpfulness, correctness, coherence, tone, bias_flag, reasoning, source_info

# Charts and UI logic should be implemented in gradio_full_llm_eval.py using Plotly or Matplotlib
