An embodiment may involve data values and metadata defining a relational chart, wherein the relational chart includes one or more symbols, and wherein the symbols each contain a respective plurality of symbol segments. The embodiment may further involve one or more processors configured to: receive a request for the relational chart; generate markup language representing the relational chart, wherein generating the markup language involves, for each respective symbol of the one or more symbols: (i) generating a block of the markup language representing the respective symbol, wherein the block includes a unit of the metadata that defines a label for the respective symbol, and (ii) based on the data values, generating sub-blocks of the markup language that are embedded within the block, wherein the sub-blocks represent symbol segments of the respective symbol; and transmit the markup language representing the relational chart.
