Social Media Seuqnce Chart

Since 2.2.0, the dot and link series have also moved to @visactor/vchart-extension. The core package no longer exports or automatically registers DotSeries, LinkSeries, registerDotSeries, or registerLinkSeries; import IDotSeriesSpec and ILinkSeriesSpec from the extension package as well. registerSequenceChart({ VChart }) and registerSequenceAnalysis({ VChart }) register their required series. For standalone use in a common chart, import and call registerDotSeries() and registerLinkSeries() from the extension package.

The high complexity of time-series data makes it difficult for analysts to manually explore and find patterns, leading to an increasing need for visualization techniques to aid analysis in order to extract and communicate insights from event sequence datasets. For social media information, it is often necessary to show the different behaviors of different users at different times in the form of nodes and edges in the evolution of linear time, and in order to better discover the user's behavior preferences, it is also necessary to use histograms. The form of behavioral statistics is displayed. Time series diagrams based on linear time maps can show data in this scenario.

Since VChart 2.2.0, the sequence chart (type: 'sequence') has moved from the core package to @visactor/vchart-extension. Install the extension package with the same version as VChart and call registerSequenceChart({ VChart }) before creating a chart. Existing type: 'sequence' and series configuration remain unchanged.

Older versions: The full VChart bundle before 2.2.0 includes the sequence chart and does not require registerSequenceChart from the extension package. For on-demand imports, use the registration API from the matching core package. The live demos below check whether the extension registration function exists to support version switching. With 2.2.0 or later, you must still install and load the extension package matching VChart; the existence check does not replace that requirement.
