Draw a bar chart: "Main world exporters of cheese and curd" by the following data: European Union - 830,000 tons, New Zealand - 343,000 tons, USA - 343,000 tons, Belarus - 189,000 tons, Australia - 172,000 tons.

Solution:

To create the bar chart, we will represent the export volumes of cheese and curd for each country. A bar chart is suitable for comparing quantities across different categories.

Data for the bar chart:

• European Union: 830,000 tons
• New Zealand: 343,000 tons
• USA: 343,000 tons
• Belarus: 189,000 tons
• Australia: 172,000 tons

Bar Chart Construction:

1. X-axis: Label the horizontal axis with the names of the exporters: European Union, New Zealand, USA, Belarus, Australia.
2. Y-axis: Label the vertical axis as "Export Volume (tons)". Determine a suitable scale. Given the large numbers, we can choose a scale where each unit represents, for example, 50,000 tons or 100,000 tons. Let's choose 1 unit = 50,000 tons.
3. Bars: Draw a vertical bar for each exporter. The height of each bar will correspond to its export volume, scaled according to the chosen unit.
4. Scaling calculation (using 1 unit = 50,000 tons):
   • European Union: 830,000 / 50,000 = 16.6 units
   • New Zealand: 343,000 / 50,000 = 6.86 units
   • USA: 343,000 / 50,000 = 6.86 units
   • Belarus: 189,000 / 50,000 = 3.78 units
   • Australia: 172,000 / 50,000 = 3.44 units
5. Title: The chart should have a title, such as "Main World Exporters of Cheese and Curd".
6. Labels: Ensure each bar is clearly labeled with the exporter's name, and the y-axis has tick marks and labels indicating the scaled volume.
