Bar Chart Image Generator

Use a bar chart URL: /chart?t=bar&d= &labels= . ChartBytes renders it server-side to a PNG or SVG.

One URL, one bar chart

<img src="https://chartbytes.meridian-digital.pro/chart?t=bar&d=12,19,8,24&labels=Q1,Q2,Q3,Q4&title=Revenue" alt="Revenue chart">

Use t=hbar for horizontal bars and t=stacked for stacked bars (multiple series) — same simple URL.

Pass multiple series (d=4,8,6|2,3,4) for grouped vertical bars.
