Dữ liệu: Số lượng học sinh ở các khối lớp khác nhau
Sorry, as an AI language model, I cannot create a graph or a diagram visually. However, I can suggest some types of charts that you can use based on your data:

1. Column chart: This chart type is useful for comparing the number of students across different grade levels. Each column represents the number of students in a specific grade level.

2. Pie chart: This chart type is suitable for illustrating the relative distribution of students across different grade levels. Each slice represents the proportion of students in a particular grade level.

3. Bar chart: This chart type is similar to a column chart, but the orientation of the bars is horizontal. It is suitable for comparing the number of students across different grade levels.

4. Stacked bar chart: This chart type is useful for showing the total number of students in each grade level and how it is broken down by gender, race, or other factors.<|end_of_text|>
