# DataViz
DataViz is a Java library to assist in the exploration of data analysis. It is dependent on the sister package "
DataFrame".
At the moment, DataViz support scatter and line charts, but has the capacity to be further developed to support a broad
range of plot types. A heavy focus has been put on the API to make it as usable as possible. As a result, it uses many
Java8 functional interfaces to reduce boiler-plate code for users.
The package also supports input and export (e.g. to SVG, and a number of raster types).
# Example code
## Scatter chart from a CSV
```java
import net.mahdilamb.dataframe.DataFrame;
import net.mahdilamb.dataviz.plots.Scatter;
import java.io.File;
public class Test {
public static void main(String[] args) {
DataFrame iris = DataFrame.from(new File("iris.csv"));
new Scatter(iris, "petal_length", "petal_width")
.show();
}
}
```
### Example customization
A number of attributes can be used to change the appearance of the scatter chart
```java
import net.mahdilamb.dataframe.DataFrame;
import net.mahdilamb.dataviz.plots.Scatter;
import java.io.File;
public class Test {
public static void main(String[] args) {
DataFrame iris = DataFrame.from(new File("iris.csv"));
new Scatter(iris, "petal_length", "petal_width")
.setSizes("petal_length")
.setColors("species")
.updateLegend(legend -> {
legend.setSide(Side.LEFT);
})
.show();
}
}
```
Here, the side of the legend has also been moved to the right using a lambda function
