# Render a daily sales bar chart for e-mail

**Use case:** 

Renders one PNG bar chart of orders over the last 7 days, with values printed on the bars. It also returns a base64 data URI you can embed directly in an e-mail or HTML from n8n, Make or Zapier. Costs about $0.002.

## About this Actor

This example demonstrates how to use [Chart Image Generator API: JSON to PNG, SVG, PDF Charts](https://apify.com/actose/chart-image-renderer.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/actose/chart-image-renderer.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/actose/chart-image-renderer.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
