-                p The built-in <code>dataset</code> attribute from ECharts v4.0 supports data formats including two-dimensional table, key-value object, and so on. The map from data to graphic can be easily set by the <code>encode</code> attribute. This is a more intuitive way to think when developing a chart, and it saves much time writing data-converting steps for developpers. Futhermore, it saves memory since different components can share on piece of data rather than copying.
-                p ECharts supports TypedArray, which occupies less memory than array and is more gabbage-collection-friendly. For big data visualization, it is suggested to use TypedArray to improve performance.
