Bar Graph Maker

Choose grouped or stacked bars for the question you need to answer

A grouped bar graph places series next to one another inside each category. It is useful when the comparison within each category matters: for example, this year versus last year in North, South, East, and West. A stacked bar graph adds the series within each category. It is useful for seeing a category total and its parts, but it is less convenient for comparing a series that does not start at zero.

This maker accepts non-negative finite values only. Use it for counts, amounts, rates, or other measures where zero is a meaningful baseline. It does not draw negative bars, calculate percentages, decide which chart type is statistically appropriate, or infer a conclusion from the numbers. Give every category and series a specific name, and add a unit to the value-axis label when it helps, such as Orders, Minutes, or USD.

Worked example: quarterly orders

Paste this CSV to compare two years. The first row names the category column and the series; the remaining rows name categories and supply numeric values.

Quarter,2025,2026
Q1,42,55
Q2,36,48
Q3,51,46
Q4,28,39

With grouped vertical bars, Q1 shows 42 for 2025 beside 55 for 2026. Switch to stacked bars only if the combined quarterly total is the message you want to emphasize. A transparent background can suit placement in a document, while a white background is often easier to read on its own.

Readable chart data and privacy

The rendered SVG has a title and brief description, and the page shows the same category and series values in a structured table with row and column headers. That table is useful for readers who prefer precise values and reduces reliance on bar color alone. Give the series distinct names and keep values visible when the numbers themselves matter.

Category names, values, styling choices, and the generated SVG stay in the browser. In the multi-step flow, the working state is saved in this browser tab’s session storage so it can move between steps; it is not put into the URL or sent through Livewire. The SVG, PNG, and CSV downloads are generated locally. Closing the tab or clearing its session storage can remove an unfinished graph, so export a copy when you need to keep it.
