About this tool

Bar Chart Generator turns a short list of label and value rows into a clean, exportable bar chart. The input takes one row per line in the form "label, value", with optional CSV quoting so a label can contain a comma, and an optional third column that sets a per-bar color ("Sales, 42, #f87171"). Choose vertical or horizontal orientation, set the chart title and axis labels, pick a single bar color, an automatic 12-color palette, or per-row colors, and adjust width, height, font size, and bar gap with sliders. Toggle gridlines, value labels on each bar, and a transparent background. The Y axis (or X axis in horizontal mode) is computed with the Heckbert nice-number algorithm so ticks land on round values and the chart does not waste space; negative values render below the baseline; percentages, locale separators, and quoted labels are tolerated. The live preview, the copyable SVG markup, and the rasterized PNG download are all driven from a single SVG string built in your browser, so the preview is always exactly what you copy or save. Useful for slides, reports, dashboards, READMEs that need an embedded chart image, blog posts, classroom handouts, marketing one-pagers, social posts, and any quick visualization where opening a spreadsheet feels heavy. All parsing, layout, rendering, and export run locally; no data is uploaded.
