Using Local Data Visualizer

Import or paste a supported table, choose fields and aggregation, and add charts to a report. Browser-local saving is opt-in; use a JSON project download for a portable backup.

Chart limits and selected filters can reduce the data shown or exported. Review the report disclosures and field mapping before sharing. Browser Print/PDF uses your browser print workflow; saved browser data is not a cloud backup.

Choose chart images, data tables or a report

CSV, TSV or supported JSON input: check the parsed columns, number interpretation and selected aggregation before charting.

SVG or PNG: share the selected chart as an image.

CSV: choose the appropriate data export and review filters and chart aggregation; a chart table is not necessarily the original dataset.

Project JSON or HTML report: keep an editable project or a self-contained viewing report respectively. Browser Print/PDF is a separate print workflow.

Practice: compare time by team

team,hours Support,2 Support,3 Design,4

Paste this authored CSV, map team to categories and hours to values, and choose sum aggregation. The arithmetic reference is Support = 5 and Design = 4, not observed tool output. Inspect the table, filters and chart disclosures before downloading a chart or report.

Local charting questions

Why does a chart show fewer rows or categories than my file?

Filters, aggregation, chart limits and category selection can reduce what is displayed. Check the chart's warnings and data table, then inspect the chosen CSV export before treating it as a complete source-data copy.

Does saving locally put my report in a cloud account?

No cloud backup is created by the local save option. Browser persistence is opt-in and can be unavailable or cleared. Download project JSON and review exported reports for private data before sharing them.
