+
+## Solution
+You can set `wordCloudChart.fontSizeRange` to configure the font size range, which indicates the text size corresponding to the minimum and maximum values of the data respectively, in the example you gave, you can configure `wordCloudChart.fontSizeRange: [5, 40]` to achieve the desired effect.
+
+## Code Example
+
+```javascript livedemo
+const response = await fetch('https://lf9-dp-fe-cms-tos.byteorg.com/obj/bit-cloud/data-wordcloud.json');
+const dataWordCloud = await response.json();
+const spec = {
+  type: 'wordCloud',
+  nameField: 'challenge_name',
+  valueField: 'sum_count',
+  seriesField: 'challenge_name',
+  data: {
+    name: 'baseData',
+    values: dataWordCloud
+  },
+  fontSizeRange: [5, 40],
+};
+const vchart = new VChart(spec, { dom: CONTAINER_ID });
+vchart.renderAsync();
+
+window['vchart'] = vchart;
+
+```
