A Fix Common Problems

When creating data visualizations with online tools, public datasets, and code templates, it’s not uncommon to encounter some occasional problems that prevent it from working as expected. We understand that finding the source of a problem can feel frustrating. But figuring out why it broke—and how to fix it—can be a great way to learn what’s happening behind the scenes.

Reach out to ask others for advice on solving problems, and make it easier for them to help you. Clearly describe your issue, mention your computer operating system and/or browser version, and consider including a screenshot using these built-in commands, as shown in Figure A.1:

  • Chromebook: Shift + Ctrl + F5 (the show windows button), then click-and-drag the cross-hair cursor.
  • Macintosh: Shift + Command + 4, then click-and-drag the cross-hair cursor to capture screenshot.
  • Windows: Windows logo key + Shift + S to call up the Snip & Sketch tool.
