Hi, Jun. - every class which extending visualization should override `render` method. - and should have `this.transformation` which is used to convert table data.
currently, 3 transformations are available. - https://github.com/apache/zeppelin/blob/master/zeppelin-web/src/app/tabledata/columnselector.js - https://github.com/apache/zeppelin/blob/master/zeppelin-web/src/app/tabledata/pivot.js - https://github.com/apache/zeppelin/blob/master/zeppelin-web/src/app/tabledata/passthrough.js and here are few examples. - (Pivot) https://github.com/apache/zeppelin/blob/master/zeppelin-web/src/app/visualization/builtins/visualization-linechart.js - (Columnselector) https://github.com/1ambda/zeppelin-highcharts-heatmap - (Columnselector) https://github.com/1ambda/zeppelin-highcharts-bubble/blob/master/index.js since PassthroughTransformation is not that useful, you can ignore. Thanks.
