Question 1

What is a Voronoi diagram?

Accepted Answer

A Voronoi diagram is a diagram that partitions a plane into regions based on which of several points (seed points) is closest. Each region (Voronoi cell) indicates that the points within it are closer to one particular seed point than to any other seed point. This diagram is applied in various fields, such as the area of influence from a given location and nearest-neighbor search.

Question 2

How do I enter data for a Voronoi diagram?

Accepted Answer

Enter the coordinates of the points in the text area inside the "Data Input" card. Data format: Enter one point's coordinates per line in the form x,y. You can separate them with a comma, space, tab, and so on. Example: 10,20 50,60 30 80 Re-parse: After editing the data, press the "Re-parse" button to reflect it in the graph.

Question 3

What can I configure in the Voronoi diagram options?

Accepted Answer

In the "Display Settings" section, you can adjust the following items. Show/hide points: Toggles the display of the seed points. Show/hide links: Toggles the display of the lines connecting the points (Delaunay triangulation). Point size and color: You can change the size and color of the seed points. Link width and color: You can change the thickness and color of the lines. Cell boundary width and color: You can change the thickness and color of the boundary lines of the Voronoi cells.

Question 4

Can I manually set the min and max domain of the X and Y axes?

Accepted Answer

Yes. If you uncheck "Auto-set the min and max domain of the X and Y axes" in the display settings, you can manually enter the minimum and maximum values of the X and Y axes.

Question 5

Can I change the aspect ratio of the Voronoi diagram?

Accepted Answer

Yes. You can change the aspect ratio by dragging the bottom-right corner of the preview screen.

Question 6

How can I save the chart as an image?

Accepted Answer

Click the "Download Image" button below the preview area to download your chart in PNG/JPEG/SVG format with your chosen quality. If you want to change the aspect ratio, drag the handle at the bottom-right corner of the preview frame to adjust it.

Question 7

Is there an auto-save feature?

Accepted Answer

Yes, there is. Your chart data is saved automatically to your browser's local storage. When you reload the page, or close and reopen your browser, you can restore the saved data. You can also revert to the default data by pressing the reset button at the top-right of the data input area. Local storage data is saved only in your browser and is not shared with other users. If local storage is disabled in your browser settings, the auto-save feature will not work. Clearing your browser cache will also delete the saved data.

Question 8

How do I save my data temporarily?

Accepted Answer

Click the "Save & Publish Chart" button below the preview area to temporarily save your chart. You can re-edit it later using the URL and password issued when you saved it. You can also publish the chart publicly via URL.

Question 9

How do I load saved data?

Accepted Answer

You can load a chart using the "Resume from Saved Data" button. When loading, enter the URL and password issued when you saved it.

Question 10

Can I bulk-enter data via CSV or copy & paste?

Accepted Answer

Open the dialog from the "Bulk Input" button, then copy and paste from a spreadsheet/Excel or an HTML table, or select a CSV file. Please check the screen for what to enter in each row and column. After pasting, edit it in the preview and click "Confirm & Apply" to reflect it in the chart.
