Use map like so:

return (
    <div>
        <ul>
            {props.data.map(({ db_keyword, db_frequency }, index) => <li key={index}>Keyword: {db_keyword}, Frequency: {db_frequency}</li>)}
        </ul>
    </div>
);

Use map to loop over items, and return the element you want, e.g. <div>, <h1> etc.

return (<div>
  <ul>
    props.data.map((item, i) => <li key={i}>{`Keyword: ${item.db_keyword}, Frequency: ${item.db_frequency}`}</li>)
  </ul>
</div>
