This example displays a single row of tabular RNA tissue expression data as a formatted JSON object. The code loads a CSV file containing gene expression values measured in nTPM across various human tissues, then converts the numeric field to a number type. Using the Vega dataset import and a simple container assignment, it renders the first record’s fields and values in a monospaced preformatted block. The visualization highlights the raw data structure rather than aggregating or plotting the expression levels.
