Hierarchical bar chart generator

Hierarchical bar chart

Combine parent-child indentation with bars so readers can compare magnitude across a hierarchy. Create a private, publication-ready hierarchical bar chart directly in your browser without transmitting sensitive rows off-device. Data is processed locally on your hardware with zero server uploads, enabling instant export to SVG, PNG, and Excel data.

Edit the data, then export.

Everything runs in your browser. Your data is not uploaded.

Data

Paste tab-separated data from Excel or edit the cells directly.

Paste or import table data

Paste a header row, or choose a local CSV/TSV file. Files are read in this browser and capped at 500 rows.

SVG, PNG, and Excel exports are generated locally in this browser. PowerPoint export is temporarily unavailable while its dependency path is reviewed for a high-severity image parser advisory.

Hierarchical Structure & Parent-Child Nesting

A hierarchical bar chart blends the indented structure of a file tree with horizontal bars, allowing you to simultaneously view parent-child relationships and compare their magnitudes. As you navigate the data, parent nodes can be expanded or collapsed to reveal granular child breakdowns or high-level aggregations. All parsing, aggregation, and rendering processes occur locally on your machine, ensuring your data is never uploaded to an external server.

Tree Data Representation & Branching

Format input columns for hierarchical bar chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.

Sample Node Hierarchy

| Node ID | Parent ID | Revenue |

Ensure sufficient visual distinction for hierarchical bar chart marks across standard and high-contrast viewports.
Align text labels horizontally whenever possible to improve cognitive readability for hierarchical bar chart elements.
Double-check scale boundaries and zero-anchors before exporting hierarchical bar chart presentation artwork.

Data shape: Node id, parent id, and numeric value columns
Exports: SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.

How it works

You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.

Frequently asked questions

How deep can hierarchies go in a hierarchical bar chart?

Two to three levels of nesting remain highly readable; beyond that, a Treemap is recommended.

Cluster treeArrange a parent-child hierarchy in a compact dendrogram to emphasize related branches and depth.Open Icicle chartReveal a hierarchy as nested horizontal bands whose area represents leaf-level contribution.Open Indented treePresent parent-child relationships as an indented outline that is easy to scan and export.Open Nested treemapCompare hierarchical composition with nested rectangles sized by leaf-level contribution.Open Radial cluster treeShow a hierarchy as a circular dendrogram when branch structure must fit in a compact footprint.Open Radial tidy treeDisplay hierarchical connections radiating from a center root node.Open
