Ask Lumen which islands have the most penguins and it writes the SQL, runs it, and draws the chart in a split-screen explorer. Drag in CSV, Parquet, JSON, or Excel files, or point it at a database, and mark extra files as metadata so the model understands what each column means. Every answer lands in its own exploration, with follow-up questions nested beneath it, and the generated SQL or Vega-Lite chart specification sits in an editor you can change to update the view instantly. Tables sort, filter, and paginate, charts carry tooltips and annotations, and results export as CSV, Excel, PNG, or PDF. Report mode gathers all explorations into one document that downloads as a notebook with every question, query, and visualization ready to rerun. A planner agent breaks hard questions into steps, a validation pass checks that the answer matches the request, and settings choose among OpenAI, Anthropic, Ollama, and other language model providers. Developers can add custom agents, tools, and analyses, or write declarative specifications that become shareable dashboards.
