  3. The right-hand box shows the generated Chart.js JSON for exporting or tweaking.
  4. Click Choose File to import a .txt or .csv file with data.
  5. Use Copy Output or Export to File to save the chart config.
  6. Use Clear All to reset everything and start over.

What Visualize Time Series can do:

  • Instantly converts time-value pairs into a rendered line chart.
  • Outputs a full JSON object usable with Chart.js or other tools.
  • Flashes the output on updates so you know it’s working.

Tool Options:

  • Smooth line curve: Applies tension to make the chart line curved.
  • Show data points: Adds circular points to each data value on the graph.
  • Fill under line: Shades the area beneath the line to emphasize trends.

Example:

2025-01-01, 5
2025-01-02, 6
2025-01-03, 4

With all toggles on, you’ll get a smooth curved line chart with shaded area and visible data dots. The JSON output is automatically updated in the right-hand box.

Common Use Cases:

This tool is great for quickly previewing time series datasets, generating Chart.js-compatible configs, testing visualizations, or converting date-value logs into readable trend graphs. Whether for reports, dashboards, or data cleaning, Visualize Time Series makes it fast and easy.
