在AWS QuickSight中，地理地图可视化的最大数据点限制是100,000个数据点。

以下是一个使用Python的代码示例，用于在QuickSight中创建地理地图可视化：

import boto3

# 创建QuickSight客户端
client = boto3.client('quicksight')

# 创建数据集
response = client.create_data_set(
    AwsAccountId='YOUR_AWS_ACCOUNT_ID',
    DataSetId='YOUR_DATASET_ID',
    Name='YOUR_DATASET_NAME',
    PhysicalTableMap={
        'YOUR_TABLE_NAME': {
            'RelationalTable': {
                'DataSourceArn': 'arn:aws:quicksight:us-east-1:YOUR_DATASOURCE_ARN',
                'Schema': 'YOUR_SCHEMA',
                'Name': 'YOUR_TABLE_NAME'
            }
        }
    },
    LogicalTableMap={
        'YOUR_TABLE_NAME': {
            'Alias': 'YOUR_ALIAS',
            'Source': {
                'PhysicalTableId': 'YOUR_TABLE_NAME'
            }
        }
    }
)

# 创建分析
response = client.create_analysis(
    AwsAccountId='YOUR_AWS_ACCOUNT_ID',
    AnalysisId='YOUR_ANALYSIS_ID',
    Name='YOUR_ANALYSIS_NAME',
    SourceEntity={
        'SourceTemplate': {
            'DataSetReferences': [
                {
                    'DataSetArn': 'arn:aws:quicksight:us-east-1:YOUR_DATASET_ARN',
                    'DataSetPlaceholder': 'YOUR_DATASET_PLACEHOLDER'
                }
            ],
            'Arn': 'arn:aws:quicksight:us-east-1:YOUR_TEMPLATE_ARN',
            'DataSetPlaceholder': 'YOUR_DATASET_PLACEHOLDER'
        }
    },
    Permissions=[
        {
            'Principal': 'arn:aws:quicksight:us-east-1:YOUR_USER_ARN',
            'Actions': [
                'quicksight:DescribeAnalysis',
                'quicksight:DescribeAnalysisPermissions',
                'quicksight:UpdateAnalysisPermissions',
                'quicksight:QueryAnalysis',
                'quicksight:UpdateAnalysis'
            ]
        }
    ]
)

# 创建可视化
response = client.create_visualization(
    AwsAccountId='YOUR_AWS_ACCOUNT_ID',
    DataSetId='YOUR_DATASET_ID',
    Name='YOUR_VISUALIZATION_NAME',
    SourceEntity={
        'SourceTemplate': {
            'DataSetReferences': [
                {
                    'DataSetArn': 'arn:aws:quicksight:us-east-1:YOUR_DATASET_ARN',
                    'DataSetPlaceholder': 'YOUR_DATASET_PLACEHOLDER'
                }
            ],
            'Arn': 'arn:aws:quicksight:us-east-1:YOUR_TEMPLATE_ARN',
            'DataSetPlaceholder': 'YOUR_DATASET_PLACEHOLDER'
        }
    },
    Permissions=[
        {
            'Principal': 'arn:aws:quicksight:us-east-1:YOUR_USER_ARN',
            'Actions': [
                'quicksight:DescribeVisualizations',
                'quicksight:ListAnalyses',
                'quicksight:DescribeAnalysis',
                'quicksight:CreateDataSet',
                'quicksight:QueryAnalysis',
                'quicksight:UpdateAnalysis',
                'quicksight:UpdateDashboard',
                'quicksight:DeleteDashboard',
                'quicksight:DeleteDataSet',
                'quicksight:DeleteDataSource',
                'quicksight:DescribeDataSet',
                'quicksight:DescribeDashboard',
                'quicksight:DescribeDataSetPermissions',
                'quicksight:DescribeDataSource',
                'quicksight:DescribeDataSourcePermissions',
                'quicksight:PassDataSource',
                'quicksight:CreateDashboard',
                'quicksight:DescribeDashboardPermissions',
                'quicksight:UpdateDashboardPermissions'
            ]
        }
    ]
)

请注意，上述代码示例中的"YOUR_AWS_ACCOUNT_ID"，"YOUR_DATASET_ID"，"YOUR_TABLE_NAME"等变量需要根据您的实际情况进行替换。此外，还需要确保您具有必要的权限来执行这些操作。
