Describe the chart you want in plain language and receive a rendered visual, using a chat-style prompt instead of a chart configuration panel.
Go beyond charts to structured diagrams, so process flows and relationships can also be produced from a written description.
No installation or local setup is required — open the site, type your request and work from the generated output.
