6 . The method of claim 3 , wherein:
the identified presentation template includes a set of named cells within which data is presentable;
generating the markup language representation of at least some data columns of each row of data included in the dataset of the first message includes mapping, in the markup language representation, each of the at least some data columns to a named cell of the identified presentation template; and
the identified presentation template is a row template, which when rendered, is rendered a number of times equal to a number of rows included in the dataset of the first message.
7 . The method of claim 6 , wherein cells of the set of named cells of the presentation template that do not include a mapped data column within the markup language representation are omitted from a visual rendering generated based on the second message and the identified presentation template.
8 . A non-transitory computer-readable medium, with instructions stored thereon, which when executed by at least one processor of a computing device, cause the computing device to:
receive, via a network from a presentation server, a message including a dataset having rows of data organized in columns, the rows of data received in a format presentable within a presentation template;
identify and retrieve a presentation template;
populate the retrieved presentation template with data from the received message;
format data populated into the retrieved presentation template according to formatting property data included in the received message; and
present, on a display device, the presentation template populated with data.
9 . The non-transitory computer-readable medium of claim 8 , wherein data populated into the retrieved presentation template for which formatting data is not applied is formatted according to formatting properties of the presentation template.
10 . The non-transitory computer-readable medium of claim 8 , further comprising:
receive event input, the event input received with regard to a data element included in the presentation of the template populated with data;
generate and transmit, via the network, a request including an identifier of the event and a representation of the data element that was received with regard to the event input;
receive, in response to the request, a second message including a dataset having a single row of data organized in columns, the single row of data received in a format presentable in a second presentation template.
11 . The non-transitory computer-readable medium of claim 10 , further comprising:
identify and retrieve a second presentation template from the data storage;
populate the retrieved second presentation template with data from the received second message; and
present, on the display device, the presentation second template populated with data from the received second message.
12 . The non-transitory computer-readable medium of claim 8 , wherein the presentation template is retrieved from the non-transitory computer-readable medium.
13 . The non-transitory computer-readable medium of claim 12 , wherein:
the non-transitory computer-readable medium stores a plurality of presentation templates, each presentation template including a template identifier; and
data of the received message includes a template identifier of the presentation template to identify and retrieve.
14 . The non-transitory computer-readable medium of claim 12 , wherein the non-transitory computer-readable medium is a non-volatile memory of a computing device.
15 . A system comprising:
at least one processor;
at least one memory;
