Automatic Generation of Visualizations and Infographics using Large Language Models

LIDA: Automatic Generation of Visualizations and Infographics using Large Language Models

LIDA is a library for generating data visualizations and data-faithful infographics. LIDA is grammar agnostic (will work with any programming language and visualization libraries e.g. matplotlib, seaborn, altair, d3 etc) and works with multiple large language model providers (OpenAI, PaLM, Cohere, Huggingface). Details on the components of LIDA are described in the paper here and in this tutorial notebook. See the project page here for updates!.

Note on Code Execution: To create visualizations, LIDA generates and executes code. Ensure that you run LIDA in a secure environment.

Features

LIDA treats visualizations as code and provides a clean api for generating, executing, editing, explaining, evaluating and repairing visualization code.

• Data Summarization
• Goal Generation
• Visualization Generation
• Visualization Editing
• Visualization Explanation
• Visualization Evaluation and Repair
• Visualization Recommendation
• Infographic Generation (beta) # pip install lida[infographics]

from lida import Manager, llm

lida = Manager(text_gen = llm("openai")) # palm, cohere ..
summary = lida.summarize("data/cars.csv")
goals = lida.goals(summary, n=2) # exploratory data analysis
charts = lida.visualize(summary=summary, goal=goals[0]) # exploratory data analysis

Getting Started

Setup and verify that your python environment is python 3.10 or higher (preferably, use Conda). Install the library via pip.

pip install lida

Once requirements are met, setup your api key. Learn more about setting up keys for other LLM providers here.

export OPENAI_API_KEY=<your key>

Alternatively you can install the library in dev model by cloning this repo and running pip install -e . in the repository root.

Web API and UI

LIDA comes with an optional bundled ui and web api that you can explore by running the following command:

lida ui  --port=8080 --docs

Then navigate to http://localhost:8080/ in your browser. To view the web api specification, add the --docs option to the cli command, and navigate to http://localhost:8080/api/docs in your browser.

The fastest and recommended way to get started after installation will be to try out the web ui above or run the tutorial notebook.

Data Summarization

Given a dataset, generate a compact summary of the data.

from lida import Manager

lida = Manager()
summary = lida.summarize("data/cars.json") # generate data summary

Goal Generation

Generate a set of visualization goals given a data summary.

goals = lida.goals(summary, n=5) # generate goals

Visualization Generation

Generate, refine, execute and filter visualization code given a data summary and visualization goal. Note that LIDA represents visualizations as code.

# generate charts (generate and execute visualization code)
charts = lida.visualize(summary=summary, goal=goals[0], library="matplotlib") # seaborn, ggplot ..

Visualization Editing

Given a visualization, edit the visualization using natural language.

# modify chart using natural language
instructions = ["convert this to a bar chart", "change the color to red", "change y axes label to Fuel Efficiency", "translate the title to french"]
edited_charts = lida.edit(code=code,  summary=summary, instructions=instructions, library=library, textgen_config=textgen_config)

Visualization Explanation

Given a visualization, generate a natural language explanation of the visualization code (accessibility, data transformations applied, visualization code)

# generate explanation for chart
explanation = lida.explain(code=charts[0].code, summary=summary)

Visualization Evaluation and Repair

Given a visualization, evaluate to find repair instructions (which may be human authored, or generated), repair the visualization.

evaluations = lida.evaluate(code=code,  goal=goals[i], library=library)

Visualization Recommendation

Given a dataset, generate a set of recommended visualizations.

recommendations = lida.recommend(code=code, summary=summary, n=2,  textgen_config=textgen_config)

Infographic Generation [WIP]

Given a visualization, generate a data-faithful infographic. This methods should be considered experimental, and uses stable diffusion models from the peacasso library. You will need to run pip install lida[infographics] to install the required dependencies.

infographics = lida.infographics(visualization = charts[0].raster, n=3, style_prompt="line art")

Important Notes / Caveats / FAQs

• LIDA generates and executes code based on provided input. Ensure that you run LIDA in a secure environment with appropriate permissions.
• LIDA currently works best with datasets that have a small number of columns (<= 10). This is mainly due to the limited context size for most models. For larger datasets, consider preprocessing your dataset to use a subset of the columns.
• LIDA assumes the dataset exists and is in a format that can be loaded into a pandas dataframe. For example, a csv file, or a json file with a list of objects. In practices the right dataset may need to be curated and preprocessed to ensure that it is suitable for the task at hand.
• Smaller LLMs (e.g., OSS LLMs on Huggingface) have limited instruction following capabilities and may not work well with LIDA. LIDA works best with larger LLMs (e.g., OpenAI GPT 3.5, GPT 4).
• How reliable is the LIDA approach? The LIDA paper describes experiments that evaluate the reliability of LIDA using a visualization error rate metric. With the current version of prompts, data summarization techniques, preprocessing/postprocessing logic and LLMs, LIDA has an error rate of < 3.5% on over 2200 visualizations generated (compared to a baseline of over 10% error rate). This area is work in progress.

Naturally, some of these limitations could be addressed by a much welcomed PR.
