==== User Story ====
> As a Wikipedia editor, I want to be able to define a translatable title for charts so that readers have context for the chart they are viewing in their local wiki language.
==== Design
The styling of chart titles, including subtext, is defined in T375235.
==== Acceptance Criteria ====
[ ] It's possible to define a `.chart` file that accept a new parameter `title` for all chart types (line, area, bar, pie) with a map of language codes to title names (e.g. `{ "title": { "en": "Energy Sources of Canada" } }`.
[ ] Charts do not automatically pull the title from the tabular data description.
[ ] Charts with a title defined render the title of the chart on preview in the appropriate language of the wiki if available.
[ ] Charts with a title defined can be embedded in an article to render a chart with the title in the appropriate language of the wiki if available.
[ ] Chart titles wrap across multiple lines if they are too long to fit inside the preset dimensions.
[ ] The chart title on the SVG returned by the chart render service is readable in full e.g. when JavaScript is disabled
[] For extremely long titles we should truncate the title.
