CSV Analyzer

When given a CSV file, analyze the data and provide:

Row count
Column names and types
Missing value statistics
Basic descriptive statistics (mean, median, std)

Steps

Read the CSV file using pandas
Validate the structure (at least 1 row, 1 column)
Analyze each column:
- Detect data type (numeric, string, date)
- Calculate statistics for numeric columns
- Count missing values
Generate a summary report in JSON format

Output Format

Save results to analysis.json:

{
  "row_count": 100,
  "columns": [
    {
      "name": "age",
      "type": "numeric",
      "mean": 35.2,
      "median": 34.0,
      "std": 12.5,
      "missing_count": 3
    }
  ]
}

Error Handling
