The Chart block displays interactive data charts including bar charts, column charts, line graphs, and pie charts. Use it to visualize data, demonstrate graphing concepts, or present information visually. This is a display block for teaching and demonstration. learners can view the chart and its underlying data.
Charts are automatically generated from the data table you create. Edit the table to update the chart in real-time.

When to use Chart blocks

Chart blocks work well for:
  • Displaying data from experiments or surveys
  • Demonstrating how to read and interpret graphs
  • Comparing quantities visually
  • Teaching data literacy and statistics concepts
  • Presenting information in an engaging visual format

Tips for teachers and parents

Best practices:
  • Choose the chart type that best represents your data; bar/column for comparisons, line for trends, pie for proportions
  • Show the data table alongside the chart to help learners connect raw data to visual representation
  • Use appropriate axis ranges to accurately represent your data
  • Keep data sets simple for younger learners. 3–5 categories works well
  • Use charts to introduce graphing concepts before asking learners to create their own
