Tips
Use consistent colors — stick to 2-3 colors per chart to keep it readable and professional.
Keep labels short — abbreviate long labels (e.g., "Jan" instead of "January") for cleaner charts.
Choose the right chart type — use Bar for comparisons, Line for trends, Pie for parts-of-a-whole, Radar for multi-variable comparisons.
Download as SVG — use SVG format when you need to resize the chart without losing quality.
Set a dark background — dark backgrounds make charts stand out in slide decks and presentations.

FAQ
The tool supports five chart types: Bar charts for comparing values, Line charts for showing trends over time, Pie charts for showing proportions, Doughnut charts (similar to pie with a hole in the center), and Radar charts for comparing multiple variables.
There is no hard limit. You can add as many data rows and series as you need. The data scroll area allows easy navigation through large datasets.
Currently each data series is automatically assigned a distinct color from a curated palette. The background can be set to White, Dark, or Transparent.
PNG is a raster format at 1200x800 pixels — great for most uses. SVG is a vector format that scales infinitely without losing quality, ideal for print or when you need to resize the chart.
