        if (columns.find(name) == columns.end()) {
            throw std::runtime_error('Column not found');
        }

        // Convert the string data back to the requested type
        std::vector<T> column_data;
        std::transform(columns[name].begin(), columns[name].end(), std::back_inserter(column_data),

        DataFrame df;

        // Add columns with different types to the DataFrame
        df.add_column<int>('IntegerColumn', {1, 2, 3, 4, 5});

Code Output:

IntegerColumn:    1   2   3   4   5
DoubleColumn:     3.14    1.59    2.65    3.58    9.79
StringColumn:     apple   banana  cherry  date    elderberry

Squared IntegerColumn: 1 4 9 16 25

Code Explanation:

• The Column template class represents a DataFrame column capable of storing data of any type.
• The DataFrame class mimics the functionality of a Pandas DataFrame but uses a map to store column data as strings.
• The DataFrame::add_column member function template allows adding columns with different data types to the DataFrame.
• Internally, all data is converted to strings for uniform storage, but when retrieved through get_column, it’s converted back to the requested type.
• DataFrame::display prints out column names followed by their string-converted data.
• In the main function, a DataFrame object is instantiated, and columns of different types are added.
• The DataFrame is displayed to show the contents, and a single column is retrieved and manipulated (squared integers are printed).
• Exception handling is in place to catch and report errors, such as requesting a non-existent column.
