How should I choose a chart type?

Use bar charts for category comparison, pie charts for proportions, line charts for trends over time, and gauges for single progress-style indicators. Start with what you want to emphasize: comparison, share, or change.

Why do some templates need different input formats?

Different chart types need different data structures. Grouped charts need multiple series, gauges need a current and maximum value, and heatmaps need at least two metrics to express size and color intensity.

Why does the chart look crowded when I add a lot of data?

Charts have readability limits. Once there are too many labels or visual elements, they compete for space. That usually means the data should be simplified, split into multiple charts, or moved to a more suitable large-data view.

Is this tool suitable for formal reporting?

Yes for quick chart production, draft validation, and small to mid-sized reporting. For external or formal documents, you should still review the numbers, titles, units, color consistency, and layout integration.

When is this chart generator useful?

Great when you need a quick visual from numbers, a draft for slides or reports, or when you want to compare which chart type reads best.

How do I choose a chart type?

Bars compare categories; pie shows proportions; lines show trends; gauges suit a single progress value; heatmaps or grouped charts help when you have two metrics or multiple series.

Why do different templates ask for different fields?

Each chart needs a different data shape—grouped charts need multiple series, gauges need current and max values, heatmaps need two numeric columns for size and color.

Should I download PNG or SVG?

PNG is easiest for slides, docs, and chat. SVG scales cleanly for print or handing off to a designer.

My chart looks crowded with lots of data—is it broken?

Usually it is a readability limit: simplify the data, split into multiple charts, or pick a view meant for larger datasets.
