The document discusses Canvas, a data visualization and presentation tool within Elasticsearch that allows users to pull live data and create dynamic charts, graphs, and monitors. Canvas is suited for technical users who frequently present to stakeholders and need more flexibility than dashboards. Examples shown include KPI tracking, real-time sales data, race telemetry, and real-time usage. The demo shows creating and exporting Canvas presentations that can be displayed in full-screen, shared online, or generated as PDF reports.
