<p>A chart plots the results of its query wherever the query runs, so a chart over a query that names an external
<a href="#queries">service</a> with <code>ldh:service</code> plots that endpoint's data.</p>
<p>A chart resource is easily confused with the chart layout mode in <a href="../views/">views</a>. The layout mode renders
view results as a chart on the fly, while a chart resource additionally stores the chart type as well as the category and
series information: variable names in the case of tabular results, and property URIs in the case of graph results.</p>

<p>The view runs its query wherever the query runs: against the dataspace's own SPARQL service, or against the
<a href="../resources/#queries">service the query names</a> with <code>ldh:service</code>. A view over a query that names an
external endpoint therefore lists that endpoint's resources on the page.</p>
<p>Views can be rendered in multiple layout modes: properties, list, grid, table, map, chart, and graph. They also show
the total number of results and allow result ordering by property. In the table mode, columns can be sorted by clicking
their headers; the sort order follows each column's datatype.</p>
