Last post, I resolved "rostopic issue"(with an unnecessary thing).
So, let's Visualizing IMU data!
roscore
roslaunch mpu6050_driver mpu6050.launch
rostopic echo /imu/data_raw
rviz

In rviz,
1) Set the "Fixed Frame" to "imu_link"
2) Click "Add" button
3) In the "By topic" tab, Select "Imu" and "OK"
Now, you can see the below.

rosrun rqt_graph rqt_graph
Ensure that imu_link is correctly connected to base_link.
